Ubuntu

Wireless connection is up but doesn't work for a while on startup

Asked by DBarzo

Hi,

My system is:

- Acer TravelMate 5720
- Ubuntu 9.04
- Wicd 1.5.9
- WPA2 encryption

Using hardy I have no problems. When I upgraded to Jaunty, on startup, the connection seems to be established (wicd says CONNECTED) but if I ping my router I get "Destination Host Unreachable".

This for the first 1 minute...then the connection start to works!!
Also, sometimes during surfing, the connection stop to work again and the ping not work for a minute..

PS. I've added a restart network on startup (/etc/init.d/networking restart) but it not solve..

Ok, maybe this is not a bug "per se", or it is maybe related to a new/edited feature that creates some incompatibility within my system.

I have not found a solution / cause yet..

I traced the connection with wireshark and this is the result:

The issue may depends by my router? It is a linksys WAG325N
