NetworkManager slows down skype

[Oxenfrogga]

Binary package hint: network-manager

Hi folks,

I recently upgraded my girlfriend's laptop to Intrepid.
Afterwards I found out that when we're talking via skype the quality of the connection from her to me is a lot worse than before (sometimes I could hear just noise). The problem persisted all the time (reboots, different days, ...) but vanished after
$ sudo update-rc.d -f NetworkManager remove
and editing /etc/network/interfaces by hand, followed by a reboot. Besides the sky application she could not find any other problems related to internet connections.

I have to add that she's having a WLan-card which was enabled, but not connected. Her internet connection was established via cable and the XUbuntu installation is not a fresh one, but some 1,5 years old, but always up-to-date. Additionally, I have to admit that the computer is an old one, lspci gives:

00:0a.0 Network controller: RaLink RT2500 802.11g Cardbus/mini-PCI (rev 01)
00:12.0 Ethernet controller: VIA Technologies, Inc. VT6102 [Rhine-II] (rev 74)

In a way the problem is solved, but not in a satisfying way ...

Please contact me if you need new information!

Thanks,
Harald

Thanks for the report, could you attach the interfaces file you edited? I don't know how network manager could make skype to work worse than the other way, it should be the same. Are you still facing this? Could you attach also a network manager log with the instructions provided at : https://wiki.ubuntu.com/DebuggingNetworkManager ? thanks in advance.

Hm, I made some tests and are not any more sure that this problem is due to Network Manager, moreover NM (like all the other processes) contributes to the work load and this pretty old machine is propably simply overloaded.

I'm sorry ... I would suggest closing this thread and I would reopen it as soon as I find better evidence.

Thanks,
Harald
