network stability

[jaraeez]

Hi all, I have a starnge problem which has only surfaced when I installed 10.1 (clean install). I ran MDK 10 with no problems whatsoever with regards to my eth connection. My problem is that I have an USR wireless pci nic which is running with the help of Driverloader. This is the exact same setup as I had in MDK 10, but in 10.1 I have noticed that after about 45 mins or so I get a slight lag intermittenly. When I ping before the 45 mins mark this is my result

 

PING 192.168.1.1 56(84) bytes of data.
64 bytes from jaraeez (192.168.1.1): icmp_seq=1 ttl=128 time=1.51 ms
64 bytes from jaraeez (192.168.1.1): icmp_seq=2 ttl=128 time=1.51 ms
--- jaraeez ping statistics ---
7 packets transmitted, 7 received, 0% packet loss, time 6005ms

 

& after the 45 min mark

 

PING 192.168.1.1  56(84) bytes of data.
64 bytes from jaraeez (192.168.1.1): icmp_seq=1 ttl=128 time=1.52 ms

--- jaraeez ping statistics ---
24 packets transmitted, 8 received, 66% packet loss, time 23004ms

 

To be honest I am at a complete loss as to why this is happening. I have updated 10.1, checked logs, etc.. with no clues.

Any help would be greatly appreciated..

Does nothing appear in dmesg after the 45 mins?

 

It might be worth going to linuxant for help, if they sell you software they should make it work!

[jaraeez]

Hi, thanks for the reply. Linuxant actually don't charge for my chipset :D (Ti) but I take your point. dmesg shows nothing of relevance. Strange thing is that if I replace the hd with a xp image on it, I have no problems. Do you know of any differences between 10 & 10.1 with regards to network protocols (i was think about IPv6.. but not to clued up)?

 

TIA

[Qchem]

I suppose you could try turning IPv6 off to see if that helps,

 

This post by arctic should help with that.

Cheers for the reply. For now I think its been fixed (I hope!) I after nearly giving up decided to check the AP's website (www.usr.com) for any firmware updates & noticed some beta updates. With nothing to lose & a story shortened the network seems to be stable. I will leave this PC running for a couple of days & take it from there.

 

Thanks again for your interest peeps..

I'm glad you've got it working. I'll mark this solved but if you have a regression post back and I'll remove it.
