Problems with wifi 802.11n


my E7 (Anna) causes some serious problems on some (linux based) wlan access points, e.g. a few fritz.boxes , some netgears and others.

Connecting to the access point works fine, however as soon as I start a download of a file more than aprox. 1MB or start streaming via that connection the router seems to stop working. Also all other connected clients cannont transfer any data anymore.

Somewhere on the web I found a hint that this is based on the implementation of the wlan standard 802.11n (150/300 MBit/s).
So I reconfigured those access points I normaly connect to to use 802.11g (54MBit/s) and the connection works fine.

However, recently I tried to use a public wifi service which, for obvious reasons, I could not reconfigure. This access point had the same behaviour. Downloads and streaming started just find and eventually halted.

I hoped that the update to Symbian Anna would help but unfortunately didn't.
Somewhere I found the hint to disalbe power saving mode but this didn't help either.

AFAIR there was a similiar problem with iPhone's wlan several months ago and it got fixed quickly. As Symbian does not seem to get fixed and I do not expect AVM or Netgear to fix there SW to support Symbian, as they're complete ignorants, I don't see an easy solution for that problem. I do not really mind that I cannot use 802.11n, however 802.11b or g is the least I would expect from a business phone.

Is there a way to tell the phone to use 802.11b (11MBit/s) or 802.11g (54Mbit/s) only?

Could you suggest any other workaround?

So it seems this problem is known by Nokia, however their only answer is to disalbe 802.11n on the router, which doesn't help if I cannot reconfigure the router.


problems, wifi
