Wifi problems

I bought a second-hand G1(no data plan) since I wanted to play with my phone. It ran 1.6 DMD64 stock with the newest radio; and it had WiFi problems.I did some research before purchasing and knew it could be flashed; so I tried flashing it to a modern ROM to see if that would solve the problems. After figuring out it was an American phone(I live in Holland) I managed to root it and flash CM6RC2. I now sometimes have a lot of reception; sometimes not. I tried installing WiFiReEnabler and WifiFixer; WifiFixer made connections overall a bit more stable; but half of the time I still don't have WiFi. I also tried to use my laptop's WiFi for my phone via USB; followed the instructions but failed. My phone managed to get semi-bricked 3 times in that period(stuck at G1 screen), and I tried flashing another ROM too; so I flashed CM 4 times. I'm using a Belkin N1 wireless router; switched channels, security and looked at my keyphrase.
The problems I have with WiFi:
- Not finding my router even though being quite close to it; happened only with 2 of the 5 times I flashed
- Finding my router but not connecting; happened 3 of the 5 times I flashed
- Saying that it's connected but not allowing me to browse; happened all times but WifiFixer occassionally fixes this
I'm still running CM6RC2 with Amon Ra recovery 1.7 on an American phone; my router is a Belkin N1 with firmware version 3.01.04 and hardware F5D8631-4 v3 with WPA-TKIP, broadcast SSID on, channel 4.
Is there a way that allows me to get stable internet on my phone without a data plan?

This could be either a hardware or software issue, not quite sure. Your options are listed below
1. Root and flash to a different more updated rom
2. Flash the newest radio(not sure if it effects wifi signal strength, forgot)
3. Open up the G1 and see if any connectors are loose.
Option 3 is probably out of the question, option 1 and 2 can be done by looknig into the rom bible(sticky) in the G1 dev thread, this will give you threads with new roms, how to install them etc, as well as flashing the new radio(if you have not yet done that)

I already flashed the newest radio, since I tried to install CM6 and in that guide I was instructed to flash the newest radio. I also obviously have installed CM6RC2 which is the newest version of CM.
I did read somewhere that more people had WiFi issues with CM6RC2 or deratives; I'll try running an older version of CM.
Edit: Doesn't work; at least I can't browse when I'm connected. Doing a nandroid restore right now; I'm intending to use Froyo.
In the case that doesn't work, how hard and dangerous would it be to open up my casing and look for those wires? It's second-hand, so warranty would likely not be a problem.
Thanks for answering anyway.

Is it possible that your router is using a different band?
I don't know about Holland, but sometimes different countries allow different wireless bands.
Try changing the channel on your router to something like channel 7 or 11, something varied from the norm.

Well. I found a solution. Connecting my old sitecom wl-167 which has no wireless N support seems to give me no problems.
(Holland has different channels then America, but my G1 was surprisingly already configured for Europe)
Thanks for your help anyway!
P.S. My XDA does seem to have some problems. "No route to host" when trying to post.
Edit: It appears it isn't 100% fixed; WiFi-fixer still solves it right now but it might not be the solution.
Edit 2: Well, WiFi-Fixer is able to fix my problems all of the time for now; but ocasionally I have WiFi for 10 seconds then 10 seconds no WiFi, et cetera.

Edit 3: It isn't threatening to my WiFi anymore. Thanks everyone who tried to help me.

Odd WIFI Disconnects - Is this normal?

Hi, I have read through every search thread on the galaxy mini in this forum but no luck finding something similar
I get odd disconnections from WIFI. If I tell the WIFI to never sleep, the connection is solid and never drops.
However if I have it on the default "WIFI sleep when screen turns off" (for better battery life) then randomly when I bring the phone out of sleep to use it, the WIFI does not reconnect. (The WIFI at this stage is not "scanning" or trying to reconnect it is simply "disconnected")
It reconnects fine some of the time but other times it will not have the WIFI reception bar and there will be no internet access through my router. I have to manually turn the WIFI off and on again for it to re-establish a connection. **
Any ideas why this might be happening?
I have tried this on 2 different routers with the same results
3G is completely disabled
Phone is completely stock, and I have tried a factory reset.
I have reduced lease time on my routers from "forever" to 10 hours
I have had this happen at the side of the router so it is not a range issue
Model number : GT-S5570
Android version : 2.3.5 - (Samsung updater on the phone tells me this is the latest version)
Provider : tescomobile.ie
Thanks

Is that update actually official? Everywhere I look regarding that gives me links to download from Hotfile.com, I am a bit wary upgrading from a non official source and I can't seem to find the update on the Samsung website. You don't have a link do you?
I am hesitant as the phone is only a month old and I don't want to do anything that will affect the warranty.
Thanks for the quick reply.

don't worry they are stock firmware provided by Samsung (not officially)
and they will work great

The official firmwares provided by Samsung (see sammobile.com) but flash it according to your region (for example I'm in Indonesia so I flash DXKPD) if u don't wanna void your warranty
Edit : or if u still hestitating, use KIES to upgrade your phone

[Q] WIFI is not functioning as it should

Hello guys I bought an Xperia Z1 last week and the wifi reception is very poor and i've read my threads and they say change channel and turn off wifi optimization and turn on Auto IP thing and change security code mode on the router and i tried all of them but i still get slow internet connection and my brother also got an iphone 5s and when we use speedtest and put them next to each other he gets 8mbps and i get like 0.3 to 2 maximum mbps
So do you know anything i can do to fix this problem

Try using this app to find best channel in you neighbourhood:
https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer
If that fails flash different ROMs like iHackers or even better CM11. If you're still getting same results then call Sony and tell them. They might replace your unit due to defective radio.

Yh my WiFi was poor in every room expect living room (where router was located). I never had this problem with GS2 and Galaxy Ace. At the time I couldn't flash CM cause of the UB camera issue. So I used WiFi Analyzer to find best channel to my surprise auto had set it to Channel 6 which almost everyone in the neighbourhood was at. After tinkering with router I found that channels below 11 work best. After tinkering with the app I found a rating system that suggested best channels.
The reason why I suggested you flash other ROMs is to find out whether its a software issue if every ROM fails then its a hardware issue unless your phone WiFi works with other routers. If the latter was the case then something is wrong with your router.

[Q] - Nexus 6 Wifi Slow

Hello All,
Just got a nexus 6 and went ahead and installed a custom rom (Pure Nexus).
Not sure if its a ROM issue or not (Trying a different rom shortly), but my wifi is terribly slow. I put it next to my amazon fire tablet and ran a speed test multiple times.
Amazon - Avg is 15-20
Nexus is 5-7
I have read some forums that says changing the band helps or forgetting the network and readding but no luck.
Anyone else have any tips before I have to send it back for a new one?

How old is your router?

Less than a year. ATT UVerse provided router.

No problems here, I did a 135 down and 50 up on Comcast router

Looks like something with the Rom. I put Chroma on it and now get around 20 down. I do not think its app related as I just restored all using TB.
Going to clean flash pure and try again.

It's not Pure Nexus, but something else. I'm getting 160 down, 12 up (802.11ac) on Pure Nexus. Have you updated your device's baseband to the latest?

Stock ROM, 802.11n, reaching ISP cap of 60/10 on web speed tests.

Found out it was a rogue app that caused it. Thanks for your responses. Can you point me to the latest baseband? I saw the Modem Collection thread here but the latest looks to be for the M preview back on 7/10?

Go to Google's firmware page and download the latest firmware package. Extract the files inside. I believe there will be an additional archive in the firmware package that you can extract that will contain the radio image.

I was having slow WiFi issues too. I updated the firmware on my router and switched the channel and now it flies.

That's not so easy to do when the entire 2.4GHz band is congested with connections, as it is in my area. Simply changing the channel didn't work for me, and I had to get new hardware that supported 5GHz. The gamers and video watchers in the house all appreciated it.

Other phone is same?

my problem previously was the same..i tried it with stock and aosp based roms, then i went to asked my sister to call our isp.. and the technician was able to verify the problems.. it was our internet cable.. they replaced it and it worked back to normal..

I had a similar problem, but only with the 2.4Ghz band, I live in an apartment complex and in Los Angeles so it's even worse. Luckily nobody uses the 5Ghz band so that works fine for me.

Update but found out that the issue is that my wifi slows down when my BT is on. Does not have to be connected, just have to be on...

Another Update is that I found out the combo is...
Wifi Connected + BT on (Does not have to be connected) + RetailMeNot App
I froze RTMN and now there is no slowness.

So the app is the culprit, not the combination of bluetooth and WiFi. Good thing you got it sorted.

XZ2 (H8296) Wi-fi problem

Hello! So I have a very strange (and annoying) wifi problem with my phone. The signal tends to drop even though it is at moderate strength... For example, I currently have a OnePlus 5t and the XZ2. However, when I walk into a room down the hall from where my router is, my OnePlus still receives a stable wifi connection (although at half speed). My XZ2 ALSO receives the same strength of wifi HOWEVER any time i perform a speed test or start a netflix video or watch youtube, the speed of the wifi on the XZ2 gradually but quickly goes down and then the wifi disconnects which leaves me on data. Autonetwork switch is turned off. This problem has become very annoying as I can no longer stream netflix in bed and I don't want to have to return this phone simply because of this very jank wifi issue. The only time I seem to be able to get a stable wifi connection is when I am in the same room as the router. Every other device in my apartment connects to the router just fine. I have tried rebooting the router and rebooting my phone.
I have also tried software repairing the phone to no avail... Maybe this is just a problem with bad hardware?

May you want to reinstall the system with the newflasher including a fullwipe.
Or may you want to use the H8266 firmware?
I use the German H8266 firmware on my h8296 without WiFi problems.

Use xperifirm from XDA
It will download the firmware for you
The newflasher from XDA will flash it for you
You only need to put the newflasher file into the firmware folder downloaded by xperifirm.
You don't need an unlocked bootloader.
And it will remove your apps, you may want to use Google backup.

I flashed the h8266 usa android 9 firmware and the problem was not fixed... Still same issue. Phone says the connection is pretty good (only one bar missing), then whenever I actually use the internet, speed diminishes and eventually loses connection from the router.
EDIT: it says for some reason the network is "disabled" on my phone

Does it happen with different Wi-Fi's?
Since pi I can't hear Bluetooth audio without stuttering on my old company ThinkPad t440p with Bluetooth 4.0.
While my old ThinkPad t460p with Bluetooth 4.1 is fine.
There wasn't any problems in Oreo.

My router has a 5.0 and 2.4 ghz setting. Both are affected by this issue. The phone doesn't disconnect from other routers I've encountered but its hard to recreate the same circumstances to match the situation of my apartment.
The peculiar thing is that when scanning, the networks still show up. But, for whatever reason, after connecting and using the internet for like, 5 seconds, it would disconnect itself even though the signal is ok (not full but definitely strong enough....). After it disconnects, the network will still show up on the scan and I can reconnect for it to work for 5 more seconds.
EDIT: Also, no other phones are effected by this problem. Not even my roommate's older phone. It is only my XZ2...

Also worth noting that this only happens when there is my bedroom wall in the way. If the phone and the router are in the same room, then everything works perfectly.

I'm in my room too and I don't have any dropping

Very strange... perhaps it could be an app I have installed? However, none of them should affect the wifi...

Quick update. It does appear to only happen with my router... When the wifi signal is weak on other routers, my phone stays connected. However, when it is on my specific router at home, a moderately strong signal is enough for it to drop.

Maybe you want to look into the router settings and only enable the newest 2.4ghz technology.

I just tried that and it didn't work... I'm about ready to give up on this phone to be honest. This is the only device that has this issue in our apartment and we have over 20 devices. It's just weird the phone stays connected until I actually want to use the internet.

Which hardware revision do you own?
Should be on the package.
Did you contact Sony support?
I did it with my Bluetooth pie problem, told them Bluetooth 4.0 is not stable anymore.
How old is your router?
My Fritzbox 7170 and Fritzbox 7490 are working fine.
Did you change the wifi frequency to an unused one?
