Dear community members, may I have your attention for the following issue:
After approximately 15 minutes websurfing in any wireless network I observe recurring birate fall-offs down to zero. The network connection itself remains stable and shows the full signal strength. It pauses half a minute before the normal speed comes back. That was the case with Dell Ubuntu and factory settings and goes on with Ubuntu 8.10 and the auto-loaded Broadcom STA wireless driver. IP address is obtained by DHCP and MTU value is set automatically.
Since I tried out different networks and Ubuntu versions, now I suspect the hardware to be buggy. Is there anybody else experiencing these temporary breakdowns? And do you have any idea how to explain or even to fix it?
