Hi,

I just got a second hand Galaxy S Plus (I9001) but the wifi is very poor. The router (Apple Airport Extreme) is about 10 meters away with no obstacles. Depending on the rom the signal strength is between -70 and -80 dBm.

The strange thing is that with the original rom that was released in the Netherlands based on Android 2.3.5 the wifi is really bad:

While with another official rom based on 2.3.6 the wifi is still bad, but a little better then the above:

And again with a custom rom (CM 10.1 as well as CM 11.0) the wifi is extremely poor:

Can somebody shed some light on this? I would like to use CM 10.1 or CM 11.0, but the wifi just becomes unusable.

thanx

Try flashing the Stock Firmware. In case that doesn't work, let the stock firmware remain and take it to the nearest service center of Samsung :D
