Bad WIFI signal - Galaxy S I9000 Q&A, Help & Troubleshooting

Hi guys
Ive been using galaxy S for a while but my wifi signal strength is very poor. I had many other phones, but the wifi strength has never been this bad. I get just one signal bar when Im in the next room from the router and the phone even disconnects very often. Could this be caused by modem version? Could you please suggest me some good modem I can use?
Thank you very much.

Reception Problem

Hi, I have a kaiser that has been dropped and there is really weak to no signal reception whatsoever and also the wifi reception is weak as well. What do you think is wrong with it? Is it the internal antenna?? Also I have the service manual, but I was wondering what the reciever was? Was it for the gps or wifi or phone reception? Please help and thank you.

If you know anything about electronics, there are some disassmbly pictures here and here. You might be able to see something loose of disconnected.

[Q] Extremely low WLAN signal strength

My N1 used to be able to get a decent signal everywhere in the house but of late it's struggling to even detect and maintain a solid connection with the wireless in the next room to the router.
I've got a laptop and iPhone in here and all of them have full bars except the N1, which keeps switching from data to wireless and back and can't maintain the connection consistently.
Any ideas on why?
Does it have to do anything with the radio/kernel?
Anyone?
I'm thinking of changing the kernel, would that help?

Try this first.
Tell the phone to forget the network, restart your router and see if reconnecting takes care of it. My notebook used to have this issue so it's worth a shot.
If that doesn't help, then you might look into a different ROM/Kernel or make sure that it's not a hardware fault with the N1 itself.
Could it be due to an OTA update that changed the radio?
The same happens to me, And it gets to a stage that it totally disconnects from wifi. It's really getting ln my nerves as we even got a booster and it doesn't help :?

same weak wifi signal on HTC Desire.

i second that. though i don't own N1, my Desire was getting full signal last year, recently i am getting very low signal as well. other devices get full signal as usual. so probably there was some update messing up.
i'll keep on searching if someone has better info to resolve.
Radio doesn't have anything to do with WiFi. Kernel does.
i'm having the same problem...has anyone found a fix?
The problem's extended significantly. Bluetooth headset usage stutters profusely, even when I'm right next to the device.
I'm pretty sure the Wi-Fi issue has nothing to do with my router, since my Desire has full signal in the same place my N1 has one bar and is struggling to get a connection.
Changed kernels, ROMs, radios, flashed engineering SPL (I know that doesn't help, however) and even a stock EPE54B ROM. No results.

Makes no difference, I even tried flashing back to stock EPE54B (fastboot).
you may also give intersectRaven's kernel a try. the one with the wifi boost.

2.6.38.6_CAVS-CM7_CFS_20110517_2251 is the one I'm trying.
Nope, Wi-Fi range still the same, Bluetooth still stuttering on the new kernel.

Possible fix to reception issues (UPDATE SOON)

Hey guys, I just increased my overall signal for my htc incredible S to 79dBm.
Now i have 4 bars instead of 2 .
Fix is easy:
You need a strip of foil, scissors and tape.
Now my palm doesn't decrease signal anymore.
I'm just wondering what i can use instead of foil, which one has less resistance.
I know gold and silver does, but hey those are way too expensive .
After getting enough responses, i will rewrite this and add [TUTORIAL] line.

UPDATED:
I'm using latest radio now, signal still low without attached cover modification, but with it I get significant signal increase.
I post step by step tutorial later! Stay tuned guys.
Is it possible to use this solution for WiFi problems as well?
If you could elaborate on what you actually did?
And what was the problem you had that prompted this?
i don't seem to be having any problem with reception atm...
Since the GB update, which I installed yesterday, I keep loosing my WiFi signal. Before the update I had a good reception. But when I hold the mobile now, the signal drops and then the icon of WiFi disappears.
Also the gsm reception seems to be worse then before.
I'm going to try the solution above and see if it helps.

I brought antenna up from palm location (Otherwise signal decreased dramatically), I'm just thinking what material have better +dBm, Getting +10dBm would be awesome .
Why i made this topic was comparison with my and my friend's phone. He have Nokia Xpressmusic, i have Inc S, and he had 5 of 5, i had 1 out of 4 atm. I try to find out material resistances. Copper wire or alu must be OK.
Gotta go to football match, See ya later!

Already tried that. Very bad reception. Keep losing signal. Doesn't reconnect
Looks like it has some kind of deathgrip.

Try without holding your palm on cover, still poor signal?
And how many metres is your router away, is this forced with 100% output power?`
Try with other devices, if still persists then this may be caused from corrupted Radio.
Hope I helped.

It's quite a distances to the router.
Is there a possibility to reflash the phone?
Death grip here too. Would appreciate a solution.
Select settings: wireless & networks: mobile networks: gsm and wcdma.
Next select settings: about phone: network.
Hold in hand and see connection drop to 0asu eventually.

The GB update seems to have raised the "signal strength minimum value", so that it shuts down wi-fi at a higher signal strength than on 2.2.
it seems to be part of android 2.3
This should explain why when I tested Incredible S (with 2.2) and the Desire S (with 2.3) side by side, the Desire S dropped the wifi connection while the incredible S held the connection. (I was testing on a network with very poor signal)
Now, as it too got 2.3 - it seems the Incredible S has gotten as "bad" as the desire s.......
I hope many people report this to HTC. I did.

PLease tell me if it helped.
It looks like the reception is better in the house. So yes it works.
In my bedroom I went from 2 bars to 3 bars.
Could any of you who have the wi-fi issue try this with a different router?
It is possible the router may be faulty, or as already pointed out, the distance may be over what the router covers.
if not, this seems to be quite an issue which will need to be looked into
Ok, I´ve done a hard reset and it seems to be improved.
WiFi signal switches from fair to good and back. So I´m fine with it.

No no, before the update, I had connection in my bed. After update - same location - wifi disconnects. Signal strenght seems the same.
It's not the router.....
Guys, we have the same problem with the Desire S (chech the forums) after the 2.3.3 update. It's very likely software related (phone dropping the connect after it's under certain signal value ... viva la HTC update).
Check http://forum.xda-developers.com/showthread.php?t=1061502&page=3
I tried it but it doesn't seem to affect my signal strengt. Signal still changes between 51 dBm and 88 dBm.
better conductor

i Believe copper will work much better but its much harder to find in a thin "foil" form
btw i havnt found a design that increases reception yet but if you hold the phone upside down it helps

[Q] Wifi Signal extremely weak

Hi guys, I use the captivate as a spare phone , and sometimes to browse the internet at home. I've noticed that recently the wifi signal has been extremely weak. I'm literally right next to my router and it's showing 1 bar of reception. When i step into the next room, i get no reception at all. I was on stock firmware at the time, I have since flashed to cm10, and the wifi signal is just as bad. Can anyone help please?
I'd suggest you try a different kernel. Also, you could try to delete your saved network and re-connect to it.

Improve WiFi Reception

My GT-I9070P seems to have weak wifi reception. Next to a laptop receiving 5 bars from a hotspot, my phone is only getting one or two bars from the same hotspot. In addition, many other SSIDs that my laptop see my phone does not. Is there any way to improve the wifi reception?
Well , I have no problems here , perhaps your WiFi hardware is defective ?
Might also be a software issue .
I'm the only guy b*tch you'll ever find in XDA.

Your phone receiver is smaller than the one your notebook, so seeing difference in reception isn't a fair comparison because your notebook will always win.
The same about not seeing all ssids.
Nothing much to do about reception, but there are a couple of tweaks for networking posted on the forums.

Mine has issues too. I noticed it improved a little with custom rom JetMod But then I upgraded to JB stock with latest CoCore kernel and its back again to where it started.
I once found a website where it said that of you enter maintenance mode you can adjust the power saving mode of the wifi But when I tried That stock ROM wouldnt let me change the setting. I hope my experience is of any help.
