Which router?

Tried changing the wifi channel on it?

Hey thanks for the reply and suggestion.

I have about 7 routers spare and have actually tried them all and changed channels several times. One I went through 1-11 channels with no difference other than lower signal.

Analysing the wifi in my area, there is no-one interfering with the signal and channel 5 is the strongest for my phone.

The Wi-Fi signal bar indicator on mine never shows as full, but the actual transfer speeds are what they should be, so I reckon it's just a bug with the indicator and not really impacting on actual Wi-Fi speeds.

The only other solution I have is to try flashing a different modem.

robogo,

Thanks for your reply and suggestion. I have a little fear about flashing another modem - do you know if all are compatible with the other parts / versions?

Ray,

Thanks for the reply and experiences,

sadly its not the case for me - literally if i have 1 to 2 bars i get a very slow speed, this is within a couple of meters. When i move through into another room, about 5 meters away, the signal completely drops and it cannot see the router any more.

I will look into the modem suggestion more and try and answer my own question. Thanks for the responses again.

robogo,

If you have a Galaxy S (GT-I9000), flash modems for your phone. The worst thing that can happen is that you flash a modem that doesn't work on your network, in which case you flash a different one. I, for one, am using ZSJV5 modem, which is supposedly for the Asian market, yet it works just great on my phone and uses a bit less battery.

But then again, to flash modems you need root and CWM recovery. Or maybe even not, I am not sure. But of course, as with everything, there is a possibility you can brick your phone, but the Galaxy S is so sturdy and resistant to that the chance of bricking it is pretty low if you follow instructions. Plus, you can flash modems without using the PC directly from your phone, so the chance of bricking it gets even lower. And you can always revert to stock, just check which modem you do have (Menu - Settings - About Phone - Baseband - last 5 characters) and have it in standby too.

I am not 100% certain, but I do think you can flash a modem without root (vol up + home + power and then use the "install zip from SD card", providing you have downloaded a modem and copied it to your internal SD card).

Big thanks for your reply again robogo. I will try some new modems out and report back what i find.

Thanks again

Just to update what modem files I have tried:

BUJV3
UGKL2
XXJPU
XXJPX
XXJPY
XXJQ1
XXJVO

All rated for europe (to my understanding), so as I can keep the mobile coverage safely.

I returned to XXJVO - every single other modem file was either the same low wifi signal or worse. Any others you could recommend for the UK?

p.s. Many thanks for the assistance so far - installed CWM3 to help out with the modem swapping as a lot quicker and feels safer.

PPS: To give the history on the phone and possibly an answer to why this is happening. I did have to have the phone repaired from a failed firmware update (official through Kies) from 2.1 to 2.2, the phone was working perfectly on 2.1, then went to Samsung, came back and I have had the wifi issue since. Do you think they opened it whilst trouble shooting and knocked the antenna?
