Wifi Tether for Root Users - 3G ok but no Wifi

First off, I have tried searching for this issue, but haven't had any luck, so I thought I would give this new thread a go.
I am trying to connect via my G1's (ok Rogers Dream to be more specific) wifi internet connection but having no luck. It was working once upon a time, I guess a few variables have changed, mainly my flashing between many different ROMs. Either case I have noticed this issue only recently, on a HERO Rom, and Cyan 4.0.1.
I am able to tether through my Phone Data Plan (3G), no issues. But for Wifi, as soon as I click "Start", my phone turns off my wifi and auto. turns on 3G.
Anyone have any ideas? My last resort is to due a full restore on my phone, I was hoping there is a more simple solution. Also, I have uninstalled/reinstalled the app.
Thanks

Did you restart the phone? This happens every now and then, and a restart will fix it.

Hey, I had to apk's fo rthis the signed_andtether_1_52-pre2.apk did not work. The file labeled Signed_andtetehr_1_52.apk works everytime.

Wait, wait, wait.
You have a Wireless Connection available, why are you tethering your G1? Can't your laptop just pick up the wireless connection? I am confused.

Exactly. lol. Well what the program does is disable your wifi so you can tether using your data connection. Thats the purpose of the program. So from the way you presented your information, you want to tether using your phones wifi connection to access the wifi router from your laptop?

Well, if your laptop (or other device) only has bluetooth, you can use Wireless Tethering for Root Users to share the phone's WIFI connection over the bluetooth connection. If that is what you are trying to accomplish.... not sure.

Haha, busted. Ok, well I don't necessarily need to go through my Wifi of my phone, because yes I have it on my laptop. I just know it used to work, now it doesn't.
Secondly, to the suggestion of rebooting my phone, well I would assume that installing a new ROM would constitute a reboot. Also reinstalling the apk would probably do the same, still though, nothing fixed it.
Sometimes my depending where I am in my house I put my phone halfway between my router and my laptop to strengthen my laptop signal, so, using it as an access point.

USB tethering

What program are you using to achieve this?
Does this wear the battery down like wifi tether or if your phone is on usb the battery never drains faster than it can charge?

If the USB port you are connected to can supply the full 500mA, it will be enough power to run the tether and charge G1 (albeit very slowly). The battery will also warm up quite a bit (to about 50C). Sometimes the phone may get into a situation where it has not properly requested power from the USB controller and it will drain battery. Simply unplug and replug to fix that. It is also possible to charge faster than drain using Bluetooth tether.
The go to programs for root users would be Wireless Tether for Root and Wired Tether for Root. For stock users, check out PDAnet.

Thank you. It sounds like if I was going to set up a always on internet connection the BT is the way to go.
Here's what I'm thinking, when 7.2 becomes available from T-mo, make that my constant 24/7 connection for my desktop.
What's wrong with that plan?

There's still a hidden cap for the bandwidth I believe. Also, if you do any activity that requires low latency, wireless (as in cell, not wifi) probably won't work well.

Since this is sorta on the topic.. anyone know how to get the usb tethering feature an cyans rom to work? i click it, it makes sound on my lap top.. but then what?

My thinking was just another g1 and use my other g1 for telephone etc. This would just replace my dsl.
Wifi tether drains my battery faster than it can charge, so what are my options?

Use a dual input USB cable, like those for portable hard drives (example here). Or go over bluetooth. Or go over USB in cyan's roms.

You'd probably want to use the USB instead of BT, as using the BT radio will cause additional heat generation. BT 2.1+EDR also has a hard bandwidth cap of 3Mbps (your actual thoroughput may be even lower depending on the amount of WiFi interference in your area)

As stated already, the first problem would be the 10GB bandwidth cap/throttle. Secondly, it's likely you'll be getting less than 7.2 at times other than at night if you are in an urban area. Finally, your rt ping will be pretty poor compared to a wired internet service. That can translate into a sluggish browsing experience.
I can say all of the above because I am actually using HSDPA as my home internet access now (not staying where I am long enough to justify a DSL installation and contract).

I saw that in the Cyan roms and that was one of the things that triggered this search.
Even if I had 1.5 down that would be fine. 7.2 would be better but we'll have to wait and see on the cap.
The real question for me is which method won't run the battery down faster than it can charge?

[Q] Wi-fi management

I have a couple of questions dealing with wifi on the Captivate.
1) Is there a better way or maybe an app that will manage wifi connections better than what android does? I use my phone at work but we have to have static IP's. So every morning when I get in I have to go through all the menu levels to get to advanced wifi settings and then turn on static IP's. It saves the last settings, so thats decent. But when I go home (I also use static IP's on my home network) I have to go through and change the settings for my home network. And then when I'm out in public and use a public network I have to go back through and turn off static IP's. Its really F'ing annoying having to do this every single day. With the iphone all you have to do is set it once for each SSID and it remembers those settings for good. There's got to be a better more common sense approach to this.
2) What is the max connection speed you guys are seeing over wifi? I have an N router at home and even when I'm like 3 feet away it only connects at around 72Mbps. I realize this is pretty decent speed, but isnt N supposed to go up to 300Mbps? My Apple Mac Mini connects at much faster and its on the other side of the house.
Thanks!

maybe there's an app out there than can manage wifi profiles.. I'm not so sure about that..
although in regards with your Wireless-N router.. are you broadcasting in 2.5Mhz or 5.0Mhz? because 300Mbps can only happen if you're running in 5.0Mhz to my knowledge..

Does the captivate suport N at 5GHz? I havent seen anywhere that discusses it, but I know that a lot of phones only support 2.4GHz.
I'm going to be buying a new router next week and would be interested to find out.
Also, I was wondering, how you measure the throughput from your phone to your router?
Sent from my SAMSUNG-SGH-I897 using XDA App

Well, launcher pro has a new feature that you can make shortcuts to the specific settings i.e. apn settings or battery status. I'll do a quick search on app brain to look for one...hold on plz
EDIT: How about this one: http://www.appbrain.com/app/com.farproc.wifi.statIc

Just to let you guys know.. N routers tbh aren't necessarily needed unless you do alot of transferring files from one computer to another.. that is where the speed really kicks off..
You will need a really fast internet connection to put that 300Mbps to good use
an old WRT54G Wireless G router that does 56Mbps will be just as good as an N router with 300Mbps if your internet connection speed is only 15Mbps.. (that's mine and I have Time Warner road runner)
As to what the Captivate runs on whether is 2.4 or 5.. lol I'm not sure.. sorry

Yeah I don't understand why people care if it can have the full effect of the router. Honestly it's a phone not a computer so it wont benefit at all from it.

Finding myself curious how to setup auto to static and static to auto.. i found 'Wifi Static' I have yet to test it D: .. but I'm hoping it's what you're looking for..
gl!
btw OP http://www.appbrain.com/app/org.kman.WifiManager
I saw that.. not sure how the program would benefit you but maybe it has it's own ip managing within the wifi networks :x .. search wifi in the market one of em has to suit you

[Q] Wi-Fi Woes

Ok I have a very iritating problem.
My captivate works amazing in all ways... except one. When I'm at home connected to Wifi, within a few mins of me putting the phone down, or even mid use, the wifi will just stop working. The icon still shows it to be connected however no apps are able to actually get internet. A quick pulldown of the quick access menu and tapping wifi off and back on again gets it going great... for another 5 mins. Then the same thing happens.
Its been like this ever since I got the phone, even after flashing different roms. Now i'm running a Linksys Wireless - N router - maybe they're not playing nice?
I dont think its a hardware fault because when I serve wifi, IE the captivate is an infrastructure mode access point for 3g, it stays on consistently and my laptop can tether for 2 hours or more.
Anyone know what might be causing this?
Thanks

When you have wifi on, go to menu settings and 'Wireless and network'. In Wi-Fi settings you can change the Wi-Fi timeout.

Try goin to settings->wireless and networks-> wifi settings (menu key)advanced and set the sleeping policy to never

I've done that...
i *Think* i've fixed it. I was using WPA2 IPK encryption or whatever.. Switched back to the 64 bit crappy WEP. Wifi was on all night and all morning with no cut out.
Might be just another linksys-is-crap situation.

HI, I figured I keep my wifi woes within a singe thread so.
I have an old D Link WBS 2310 router.
I recently got a message from AT&T that I'm near my data limit. This surprised me as my last cycle I barely got near 500mb. Since my bill isn't ready yet, I can't see exactly what it is I'm doing to use so much data.
TO be safe I figured I'd pull out my old router and set it up. After hours of hassle getting it to work on my new computer, I wasn't able to get my Captivate to hook up to it.
My laptop works fine. It gets a fast wifi signal, but my phone just says "Obtaining IP address" for a while and then gives up.
My phone gets wifi at work, at friends', at coffee shops - but not at home.
I've tried this with no encryption, WEP encryption and WPA2 encryption.
Each time my laptop would hook up to the wifi but my phone wouldn't.
I searched some other forums and found similar problems with HTC phones.
Some answers say that D Link sucks. But that answer applies to other brands as well.
Do I need "n" wifi, rather than "g"?
I don't want to buy another router only to find it still doesn't work.
Any help?

part of the IEEE 802.11n standard is backward compatibility with all previous 802.11 standards IIRC, so there should be no need to buy a new n device.
HOWEVER, i am also having issues with my wi-fi and my g capable router. i will meddle around with some phone and router settings to see if i can fix this, this is one area were i can actually be of some use on this forum

Hi. It turned out the wifi was broken on my captivate. I reset it to stock and it's all better. It had been working up to the previous day so I assumed that it was still working. The router goes down intermittently in general, so I've ordered a new one to see what's up.

Hi, I'm back! So after resetting the phone and getting wifi to actually connect (rather than being stuck searching for IP address), I'm now having the exact same problem is the OP. The OP seems to have solved this by switching to WEP. I tried this and it doesn't work. My timeout is set to never. Also, it's the same at home (I replaced my router) as well as at Starbucks and a friends house.
I'm connected, but can't download or sync. It works initially and then stops, and then comes back in briefly and then stops, all the while "connected." Sometimes I can fix it temporarily by turning off wifi and then turning it back on.
SO what's the deal? Is it a hardware problem? Is there some secret magic code?
edit: Just disabled encryption - same problem.

[Q] Anyone still having wifi issues???

I have looked at every thread and forum possible for the past 2 months. My wifes nexus and my own connects to our home wifi for a few minutes then disconnects itself (weather the screen times out or not) and will not reconnect at all. I have tried the wifi fix apps on the market, changed the settings on my router numerous times, factory rest my router and phone, changed roms, and even routers but nothing seems to work. My wife's nexus is stock and not rooted so I have been using hers as a reference thinking it was maybe a rom I was using but she is having the same problem. Any ideas would be greatly appreciated.
sigep235

I had that problem but as soon as I got to 2.2.1 and/or used a newer Radio version, the problem disappeared...
Although, N1s are still very picky on routers...try with another router and check if it keeps the connection alive.
Also check your router settings to see if they're optimal (try having no password set and see if it keeps the connection...if it does then it might be a problem with the N1 not crypting information well or so)
You could also try updating the router's firmware.
Make sure your wifi policy is set to "Never" (go in wifi settings the press Menu and click on settings)
Last thing you could try is manually set an IP address + gateway + netmask in the wifi settings as well as setting your N1's mac address to that same IP address in the router...
If nothing works then, I'm completely out of solutions

I just got on to look at some of the settings with my router when I noticed that some times when my phone says I am connected to the wifi there is no IP address assigned to the phone. Under connected devices it says "android device" but with no ip address associated with it...

I still have the problem
I still have the problem. I have pretty much given up on it. I have heard that if you increase the minimum CPU speed a little, it will help. I'm not willing to do that as it will undoubtedly waste more battery.
I have changed the wifi sleep policy back to "when screen turns off", because having it on "never" would make the phone think it's connected..when it isn't..leading to hours of no email notifications and such. But I can't imagine how frustrating this must be for people who don't have a data plan or some other similar situation.
I'm thinking about getting a Wireless N router (I have a G right now) and seeing if that helps. But even if I was to get one, I don't have much money to spare so I'd probably get the cheapest N routers, around 30-50 dollars..and I don't know if those are any good...or if there really isn't any difference between the high priced and low priced ones.

I said this in another thread, but I'll say it here.
I tried all of the things everyone could suggest and none of them worked. When I heard Broadcom updated the driver and CyanogenMod put it into his nightlies, I bit the bullet, unlocked my bootloader and installed CM6 and it changed NOTHING. So I went out and bought a new router: Cisco E3000. It works great. So I guess it was a bad combination of phone and router. I had to spend hundreds of dollars. Really ****ing pissed me off. But I wasn't going to buy a cheaper router without dual channel wireless N.

Nexus has N connectivity but only on one band (2.4Ghz) and I don't think the technology matter (heck, I'm still on 802.11b ) it's really more of a phone/router combination problem...
I did actually test on my VERY CHEAP spare 802.11g router (DLink --> do not buy their products) and the connection did NOT stay...that was back when I was on stock FRG83 though...I should try again on Cyanogen but I'm wayyy too lazy ^^
btw, I really don't get why people always unlock when they wanna flash a rom....heck, keep your warranty!! there is an easy way of doing it without unlocking...meh
PS: I have a 50MB data plan (technically, I didn't buy a data plan, it came free) so I AM a heavy wifi user and it was such a pissoff to find out that my new Nexus One couldn't connect to Wifi and keep the connection alive...now I'm damn happy that it works after all that fiddling ^^
@sigep: try to assign a manual ip to your N1's mac addres...or update firmware, it definitely looks like a router problem...

The root without unlocking method wasn't too tested when I unlocked my bootloader.
I have made two swaps with no problems since.

Oh kay sorry then
Although all the new wikis and todos should emphasize on the locked bootloader methods to avoid voiding warranties...although I admit fastboot is always noobproof but I digress ^^

I've been testing several routers from different brands, and the only one that seems to work fine with mi Nexus One is the Linksys/Cisco WAG160N (802.11n, but 2.4 GHz only). However this one has other issues of its own, like not being able to connect to mapped ports after two days up and running (not even from the LAN). The N1 works fine, thought, it doesn't disconnect overnight.
I've also tried an SMC (SMC SMC7904WBRA-N, I think). This one is really bad, the router freezes after only two days of use, the lights freeze and it stops working altogether. I returned it after a week.
I'm currently using a Sitecom (300N WL-348). With this one the N1 WiFi is dropped over night, and the connection to this AP is disabled. I'm still testing if moving to a less crowded channel could fix that. I hope it does, since this router seems to have a more stable firmware that the Linksys/Cisco, same WiFi coverage (which is quite good), and even better WiFi performance. Not all is good, though, DSL performance is worse.
In the past I used Netgear routers. The firmware was stable as rock, but the hardware not so much and after a year of use they are very prone to failing. No idea if newer models are any better in this regard, they are impossible to find, so I don't think this has improved.
Since I have DSL at home, I'm looking at routers with DSL modem built in, so I don't have to have two devices (DSL modem and wireless router).

From my observarions - Nexus will disconnect from WiFi when the IP it has is lost and the network doesn't supply IP on time. After 1 or 2 IP assignment timeouts, it will skip the network and refuse to connect.
Every router I've connected to that supplied IP on time, even when revoked every X min, didn't cause disconnects.
Of course, WiFi on sleep set to "Never".

Success! Last night I updated the firmware of the Sitecom router, and changed the WiFi channels (it's set to use wide channel, so it uses two channels). This morning the N1 had still a solid WiFi connection and over night it updated all services just fine (weather, Facebook, email).

I've been using the Sitecom router since my last post with no issues. Then last friday arrived a small update that broke WiFi. On Saturday arrived the bigger update to Android 2.2.1 but the problem with WiFi remains. Before 2.2.1 Wifi has been working fine every day at home and work, now with 2.2.1 it's broken at home and work.
Are we moving forward? If Gingerbread doesn't fix this problem I'll have to do something about it: try cooked ROMs or even getting another phone . Currently my N1 keeps disabling my access points all the time.
