Intel Corporation Wireless WiFi Link 5100 latency problem


Hi all,

I have a similar problem with the wifi "n" connection (if I connect with wifi "b" or cable, works fine, and in Vista works fine in wifi "n"). My laptop it's a Toshiba Satellite A500-141, and the Network controller is an "Intel Corporation Wireless WiFi Link 5100"
When starts my laptop and 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 40 seconds. After this firts ping the answer time it's 12ms. Also disconnections happen (but network manager shows the connection established) and the ping delay 40 seconds one more time.

I try to install the intel driver, but after "cp iwlwifi-5000-2.ucode /lib/firmware" what is the next step?

This is the ping results:
jordi@jordi-laptop:~$ ping 192.168.2.1

I moved your question to its own thread. It can be confusing for members to track two separate problems in the same thread.

Hi all,
I try to install the new intel firmware "iwlwifi-5000-2.ucode", but I don't know how.
I've done: "sudo cp iwlwifi-5000-ucode-8.24.2.12 (2)/iwlwifi-5000-2.ucode /lib/firmware", but, what is the next step?
This is console result:

Hi all,
Two weeks ago, I spoke to Belkin support, and two days ago 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.
I'll speak with Belkin, but it's other problem.

Note.- It's possible mark like SOLVED?

Thank you.
