Bug Description

Dear all,

I’m using Ubuntu Jaunty 64 bits and I have a problem in my laptop (Toshiba Satellite A500-141 with Intel Corporation Wireless WiFi Link 5100 agn) with the wifi “n” connection.

When starts my laptop the Network Manager shows established connection but if I do a ping command to 192.168.1.2 (it's the router) the answer delay until 46 seconds. After this firts ping the answer time reduce until 2ms. Also, disconnections happen regulary (but network manager shows the connection established) but the ping delay until 40 seconds one more time.

If I connect with wifi "b" or cable, works fine and Vista wifi “n” connection works fine too.

The lspci command return:

I try to install the new intel firmware, but after copy the firmware "cp iwlwifi-5000-2.ucode /lib/firmware" what is the next step? Actually I have iwlwifi-5000-1.ucode installed.

Thank you very much in advanced.

Hi all,

Two weeks ago, I spoke to Belkin support, and today they send me an e-mail with a link to download a new firmware for the router.
This afternoon I've installed the new firmware and..., surprise, the ping answer was inmediatly!!!!, but the speed was the same 60Mb/s just 20inch from the router.

Now I'm about 10m from the router and the speed is reduced until 36Mb/s. It's possible to increase the connection speed?

Hi all,

We'd like to know whether this is still an issue for you. If so, please can you try with last kernel version, which is located on http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32/

Thanks in advance.

Hi Pepe,

Thank you for your answer.
I spoke with Belkin about the wifi speed connection, and they answer me that I change the wifi channel number, but I don't done it.
Yesterday, I was sending a 2GB file from my laptop to the network hard disk, and the speed was 1.4MBi/s (read from netspeed), I think that it's fine.

Now, I'm using kernel 2.6.31-17

Thank you very much
