[HELP!] My WiFi Sucks A$$ - Captivate Q&A, Help & Troubleshooting

Hey peeps. I'm on Andromeda 3 and I have been plagued lately by a very odd wireless issue that I cannot seem to fix. My symptoms will replicate no matter which wireless network that I connect to.
First off, I am an IT guy so I am very savvy. Secondly, I have been developing a theme on this phone so that may be related, but unlikely.
Some information on my setup:
In my home I have a Cisco Aironet 1200 802.11g access point that I am using for wifi behind a Cisco PIX 501 router.
At work we use Extreme Networks (enterprise grade) wireless access points with Juniper firewalls/routers/switches. I do not recall model numbers (irrelevant).
The problem:
Issue #1 - When I turn on wifi my signal bounces between 0 and 1 bar, and occasionally if the sun and moon are in the perfect positions in orbit, I will get 2 bars (wifi, not cell signal).
Issue #2 - I cannot for the life of me get a new IP address from DHCP on either network! My IP address on eth0 is stuck at 10.x.x.x but my home IP scheme is 192.168.0.x
My phone is set on DHCP, not static so I have no clue why it's binding to that address.
I have tried terminal emulator to release and renew but it doesnt work and I just end up getting an error that says DHCP timed out. Im not sure how far Android commands differ from Debian but I have tried (without success),
ifconfig eth0 down & up
netcfg eth0 down & up
dhclient (not recognized)
Other than that my host file is clogged up with a bunch of crap that I'm guessing by the ROM dev for disabling ad's.
I have even reflashed the ROM but that didn't help.
Can anyone suggest other things I can try to get that IP to unbind? The eth0 settings have to be stored away on some conf file somewhere right? I just dont where to look.
Thanks way in advance!

I have had issues with wi-fi connectivity with Andromeda 3 as well. I have found that for me, either rebooting the phone or using the power button menu to switch to airplane mode for a minute or so and then turning airplane mode off again fixes it for me - until the next time. Otherwise, I am sorry that I do not have better suggestions.

Wireless Wierdness

Help!
I have a Netgear DG834T router as provided by Sky. I have one wired and two wireless connections running into it (let's call them WD, WL1 and WL2 respectively).
On the connections page I can see all of them under "attached devices"...but now I want to connect using my Kaiser (actually an O2 XDA Stellar)
What happens...
On the Kaiser, I get an IP address (assigned by DHCP) as normal - but can't access the internet - or at least, can only access it very rarely - http://www.google.com can't be found, but http://www.bbc.co.uk can. No idea why.
On the router, under "attached devices", not only can I NOT see the Kaiser, but WL1 and WL2 also disappear. WD remains visible. The router cannot ping the IP address of the Kaiser (timed out). If I disable WiFi on the Kaiser, then WL1 and WL2 are immediately visible again. Internet connection on WL1 and WL2 works, even when they are not visible.
I HAVE connected to this network before without any problems.
What the hooting heck is going on, and how do I fix it?
Thanks!
Time to troubleshoot! What happens with this phone on another wireless network. We need to determine if it's the phone or the network. Do you have any friends with a phone like this? Can you use their phone on your network? Do you have any ROMs flashed, has this phone ever been on the network without problems?
If the phone works on another router try looking for firmware updates for the router. Those things really do need to be updated often and it could have something to do with that.
Only have access to one network :-(. Might be a couple of weeks before I can access a hotel one or something like that.
Think next door neighbour has similar phone, but different provider...will try if he'll let me!
No ROMS flashed.
It connected fine when I first had it. As far as I know, I've changed nothing since then.
2 out of 4 answered...with an option on three...I'll get back to you as soon as I've beaten up my neighbour and stolen his phone...
Joke!
There should be somewhere you can go to test that wireless. I can walk outside the building I'm in and find one.

You = US, me = UK. We still think the biro is a recent invention...
Neighbour's phone on my network gives the exact same problem. I've also noticed that when I click "Renew IP" on the Kaiser it doesn't work...it gives me 0.0.0.0, but will occasionally flash up the correct IP address. It's alomst as if the connection is being lost and remade every few seconds. The status ist gives me is "associated to network"...is that different to "connected"?
I've been trying to solve this on my router, but none of the settings seem to make any difference.
Same here
I get the same with the router from sky.
Kaiser says I have an IP address, 192.168.0.5, but the it doesn't show up on the attached devices on the router.
What I find that works is hit renew IP maybe twice until you get a really wierd IP address like
169.254.*.**, actually not sure if I'm picking up another network, but for some reason I don't think I am.
I can then browse the web and sync via wifi.
Really pisses me of that it says that it has an IP address but doesn't connect.
1) Make sure you dont have a proxy set up on your wifi connection on your device.
2) The 169. address is your device getting an unauthorised IP address as the router did not receive the correct encryption key from the device.
3) You can check if its an encryption thing by simply logging in to the router (192.168.0.1 in your web browser on pc) and changing the settings to turn wpa off and testing it. The routers username and password are on the card - its something like "sky" and "admin"
Yeah I agree, there is something up with that router.

No, proxy set-up as the device was bought unbranded in US.
Because there are issues with this router, encryption and media streaming devices, I have only restricted the mac addresses with no encryption.
Still don't know about the 169. ip address beacuse doesn't seem to come up as am ISP.
Now then, how wierd is this?
After all these issues and kind of giving up on it as a bad job, I also noticed that out on the road, my GPRS wasn't working either - TomTom couldn't connect to the "plus" traffic service.
I get on the phone to O2 who told me that my phone hadn't been "provisioned". After one false start where they didn't seem to do anything about it, I have just (literally) had them tell me to go to the O2 Operator settings and tell it to update the "O2 UK Post Pay_GPRS" and reboot.
GPRS now works. And magically, so does my WiFi - IP address negotiated and full access to internet and my router's setup page granted. Working like a charm again.
So - seems to me it's an account setting, and nothing to do with either me poor ol' router or me nice new phone.
For completeness, I was occasionally getting the 169 IP address too, so it sounds like we have EXACTLY the same problem - suggest you get onto your service provider ASAP.

[Q]Wifi droping problem

I have problem: My wifi signal drop every 60 secs approximately,on every stock rom from JVQ to the newest JVU. Last rom where wifi works great was JVQ after that version i have same problem in every single STOCK rom,JVZ,JW1,JVU... (on CM7,ICS port,MIUI I dont have that problem).
Anyone know how can i fix it? (sorry if my english is not to good)
Known problem. There is a workaround however. Set your wifi routers dhcp lease time from 0 (or never) to, for example, 120 mins. Also remove ip address reservation (if set) in your routers settings.
Used to have the same problem at android 2.2, but the 2.3.3 update fixed it. I used to assign a static IP to my device at home, that helped for the time being.
I have INTRACOM JetSpeed IAD-Wp2 router and cant find non of these settings.
Try going to 192.168.1.1 in your webbrowser on your pc, and try getting access with username and password "admin". That should allow you to configure some settings, including assigning a certain IP address to your phone.
On your phone, go to wifi settings, advanced, and enable "Use static IP address". Then configure it's settings.
You should refer to the routers manual to find out the setting for the dhcp lease time and ip address reservation. Routers and their names for these settings can differ slightly from each other.
If you set static ip in your phones wifi settings, you may not be able to use wifi anywhere but in your home network.
So the problem is my router or the phone? All these solutions that you have proposed are not long-term right? It will help me just when I am at home but if I go out somewhere that settings will not be of some help right?
The settings I posted were looked up specifically for your router, milanche911. But indeed, it'll only fix it when you're at home; you'll have to turn using a static IP off if you're elsewhere.
Does it happen to you no matter what router you use? I only had it happen to me at home, at other people's places things were fine.
try this application
it is WiFi scanner and signal checker... in config is setting scan Frequency 0-30 seconds and including the radar and WiFi sources GPS locator ...
good luck.

If the issue is the "wifi bug" which has been covered in the leaked rom threads, the culprit is the phone.
As a long-term solution, there's no harm in setting the wifi routers dhcp lease time to finite value and removing the address reservation, so that the router is not forced to give your phone always the same ip. At this point, you should not change the ip to static in your phones settings, this is what will prevent you using wifi outside your home.
Now you should find a way to check these settings in your routers configuration.
Thank you people! Thank you for your help, the problem was that I had been logging into the router settings with admin / admin and I got the complete setup for just a basic settings. Trick was that I log in with admin / tzlkisonpk and thus get full router settings where I finally found the "lease time" setting. Configured for two hours and now everything is fine. Thank a lot once again! Cheers!
Glad it worked out
tap on the keypad of your phone - >*#*# 4636 # * # * and Wi-Fi information, you can find something to help ...

No WIFI-No MAC adress or IP? what to do do??

I can't see any wifi hot spots including my own under "WIFI networks". Running latest Cybermod 7.2 on an EU milestone phone. I have no MAC IP floating or static address under "advanced settings". I wonder if that is the problem.
- Regulatory domain is set to 11 (US, my location)
- MAC address = Unavailable
- IP address = Unavailable
- Static IP address is turned off; no settings
If this is the problem, where would I find either the mac address and IP or, numbers to plugin for a static address?
Thanks much in advance,
PK
Go download apndroid.apk Google it
Thanks, downed it and installed, put a widget on my desktop, not sure what it supposed to door how I'm supposed to set the 3 radio button but it isn't helping anything at this point. Still no wifi.
PK
Go to the apndroid and enable stuff there sorry i already forgot about it
Thanks again,
Put check marks in the three boxes and made the little button on top have a green bar. Hasn't fixed anything. The main problem I think is I have no MAC address anywhere. The iI think with it in floating mode, the IP address will be given out by the WiFi hot spot.
I wonder how I can give it a MAC address.
Regards, PK
When WiFi is turned off, it will show no MAC address. Are you sure WiFi is on and searching for networks? Try toggling WiFi off/on again. Still no MAC? Perhaps your ROM isn't accessing your WiFi chip correctly.
Thanks,
Nice to know about the mac address.
The WiFi Check marks don't stay on very long....20- 30 secs. During that time it doesn't pick up any hot spots. It also doesn't find any when I use the "search" option (found by pushing settings button wile in "wifi settings" with both boxes checked).
Regards, PK
If WiFi won't stay enabled, then there's an issue with the driver. Have you tried another ROM?
Thanks,
I went from Cybermod 7.1.x to the latest Cybermod 7.2.x. I don't see that many popular roms around any more for this phone. Any suggestions?
Does the "radio" include the wifi drivers and is it possible to flash radio independently like on other phones.
PK
Post your dmesg (or logcat -b kernel) after you try to enable wifi.
Most probably it's a hardware issue.
Hello,
Thanks, could be no better person to help sort this out than you. Having trouble getting a logcat exported that is formatted it into anything other that one, big, run-on sentence. Will post as so as I can output one that is legible.
Regards, PK
suddenly lately i am reading that a lot of people have hardware problems with wifi - including myself...
That is a strange coincidence, however unfortunately it happened...

[Q] Switching between routers within the same wifi

Hey guys, I got a problem with wifi on my One. The thing is I got a couple of wifi routers in my house (one can't cover the entire building) and they're both broadcasting the same SSID, password etc. basically one is connected via RJ45 to the other and set up exactly the same way. Problem is when I move around the house and lose connection to one of my routers and the phone automatically connects to the other all my connections on the phone stop working and I have to turn my wifi off and on again. Same thing happens when I'm at my university, each floor has 2 wifi routers on it and phone tends to jump between them screwing up the internet connection each time. I know it might not be the biggest issue in the world but still it's quite annoying especially since my old SGS didn't have this problem. My phone is not branded and of course up to date. Thanks for any advice.

From my experience after installing a lot of different wifi's in different operation modes, it all depends on how exactly the routers have been setup.
But to answer your initial question- the topic at hand; as long as the wifi's broadcasts the same SSID, you cannot choose which of the two individual routers you want to connect to. Please someone correct me if I'm wrong, but afaik this is not possible. If you want the possibility to choose, then set them up with different SSID's. This would be the _easiest_ solution, just make sure they broadcasts at different frequencies with at least 5 channels apart, i.e. channel 1 and 6, or 6 and 11, or 1 and 11. These are the most popular ones in the 2.4 GHz spectrum. If you use 5 GHz you have a lot more to choose from.
Now, if it's important that your network works seamlessly (with the same SSID), I can provide a step by step guide upon request.
But the solution to your current problem, from my experience; yes you have to turn the wifi off and then on again to "force" the wlan-card on your cell phone to -faster- connect to the closest router, otherwise it will take maybe 15-45 seconds before it does this automatically. It's basically the same with computers. This mostly happens if the wlan-card are within range of both networks, but it will try to stay connected to current one before changing.
And there are some important guidelines to follow when you connect one router to another if they are from the same brand (because of the ip-range and gateway). I once had to setup 8 wifi-routers in a house, because of the size and the thick concrete walls (same SSID)...
The problem is my laptops and other phones don't seem to have this problem, also the phone doesn't 'fix' itself after 40 or so secs it just stays broken as far as I've noticed forever (or at least till i leave my house). Also it doesn't have a problem connecting to the other router, it loses connection, looks for available networks, finds my other router, connects and... nothing works. Exact same thing at the university, finds routers, connects with 5/5 bars and it just doesn't work.

Are you sure you have it setup with DHCP and not some static ip-settings? Can you post some screenshots of your wifi-settings?
If you haven't tried already, get your phone to "forget" it's settings so you have to reenter the password and make sure it's set to DHCP. But first take out the power from both your routers so they get a reboot, and make sure the ethernetcable is connected from one of the LAN ports on the main router connected to the internet (from your cable/dsl/fiber-modem), and in to the WAN/Internet port on the secondary router. Btw what routers do you use as master and slave?
Yes of course I have the routers set up just like you say And yes I'm using DHCP on both of them. They are Airlive 1600GL with tomato rom as main and WR740N as secondary. I took screenshots of what seemed relevant sorry the main router's settings are not in English but it seems that would require me to reflash it with a different rom.

What's with the DNS being 8.8.8.8 and 8.8.4.4?

These are Google DNS.
I would do it simple and solve it by changing the SSID on the slave router to something different, like wireless2, and change channel to 1. Or change the channel on the master router from 8 to 11. Your phone will probably change from one network to another faster this way, or it's at least easier for you to manually choose.
If that doesn't help, and the network is 100% problemfree for other wireless devices, I guess it must be a firmware or hardware problem with your One's wlan-card. Most likely firmware.
I will try it in the morning but still I'm pretty confident it's not the matter of setting up my home network but rather One's software bug. I can't say with 100% certainty right now but I don't remember having this issue before the update to the newest Android version.
Both routers need to be on the same subnet, enable dhcp server on one and disable it on the second one. Also set the second one as an access point only with a static ip in the same subnet.
The problem you have now is that wireless clients must negotiate a new ip when switching routers because of different subnets assigned to each.
Let me know if you need more details.
But still that would fix the problem at my home, what about when I'm somewhere else?
What ROM are you running? I leave wifi enabled all the time and haven't had any issues moving between networks, it automatically connects when another network is in range.
Android 4.3 with Sense 5.5 all stock not even rooted.
Since your completely stock it should just work. I'd try fixing the home network first and see if that solves the issue at home, then move on to trying to figure out the network issue at school.
Router1 - master
Internet connected to wan port
Cable from lan port to a lan port on router2
Dhcp: enabled with an ip range of 192.168.1.100 and up
Lan ip 192.168.1.1
Channel 1
Router2 - slave
Nothing connected to wan port
Cable from Router1 lan port to lan port on this router
Dhcp: disabled
Lan ip 192.168.1.2
Channel 11
Set ssid and wpa settings the same on both routers.
With this setup clients can hop from one access point to the other without a dhcp request or ip change, should switch within seconds.

Tried that setup for many times over the years I've worked with routers, from my experience that is unstable.

iptables help...

Where to start, ok i have a note 5 tmob with stock rom rooted and posiden kernel and latest firmware. I have been tweaking the system for securty. Vpn af+wall adaway ect...
I also use a wireless sniffer called wicap 2 for keeping tabs on my internet.
So to my point or maybe problem. I was sitting with my daughter showing her some security issues to watch out for namely the difference between http and https. So while i showed her what happens if i log in to a site without https and my sniffer running i caught my fake log in and showed her. Then commenced to have her do that to on her phone.
Thats when the problem popped up. I did not catch her traffic.
I looked into my firewall and iptables. I noticed my wlan did not seem right
"wlan0 Link encap:Ethernet HWaddr EC:1F:72:EF:BE:21
inet addr:192.168.0.5 Bcast:192.168.0.255 Mask: 255.255.255.0"
My log on my sniffer says my wlan0 address is 192.168.0.5/255.255.255.0 aswell.
Now my router is ip address 192.168.0.1 and my phone is the one that ends with the "5". Shouldn't my iptables look at my router ip and the go up. Instead of starting at "5" from my phone ip and missing the first 3 ip addresses while sniffing.
Now if this is not right how do i change this. Thanks in advance and i hope i have put enough info.
I do not know the program but sniffing works in one of two ways on your phone it can set up a vpn and see everything but for another phone the network card needs to be set into promiscuous mode to see packets not designated for you this means the proper network card. So it would seem that you are sniffing only your own network packets. And DHCP is not affected at all the numbers do go up but by sniffing you are seeing all network traffic.
