just a quick update

since I reinstalled the PCI card this morning the connection has been stable and the email thing seems to be sorted out, last night it was hellish and I haven't done anything different that I'm aware of, the only thing at the moment is the download speed which may or may not indicate there is still a problem

Just thought I post this because I don't want to waste anyones time

If it happens again .. see if this makes any difference, run:
Code: [Select]
sudo modprobe -r rt2800pci
then
Code: [Select]
sudo modprobe rt2800pci nohwcrypt=1

That will NOT survive a reboot .. but if it helps, we can make it permanent.

Ok thanks

I'll just monitor it meantime, if it happens again I'll do what you suggest

Any thoughts on the slow download speed, to be honest it's not causing any obvious problem, you tube videos play ok although a bit stuttery on full screen ?


Many thanks

On that PC it could be the hardware decryption .. which is why I suggested disabling it :)

Well if that's the case then there's no harm in trying that now to see if it improves the download speed if it has an adverse effect then all I have to do is reboot ?

Code: [Select]
pat@Linux2 ~ $ sudo modprobe -r rt2800pci
pat@Linux2 ~ $ sudo modprobe rt2800pci
sudo: unable to resolve host Linux2
pat@Linux2 ~ $

The first command disconnected the network, the second command re-connected

OK, dunno why you're getting the sudo error message .. but sudo is obviously working

Run these again
Code: [Select]
sudo modprobe -r rt2800pci
then
Code: [Select]
sudo modprobe rt2800pci nohwcrypt=1

and see if the download speeds have improved.

OK I would say there's no significant change after the changes,

running the speed tests are naturally inconsistent anyway so I ran the test 3 times with and without the changes

before changes  13.12mb/s  6.55mb/s  10.05mb/s   average  9.90mb/s

after changes      11.10mb/s  13.05mb/s   10.90mb/s  average 11.68mb/s

so although I had a slightly faster average after the change the highest speed was achieved without the change

I'm not really sure if this is even a problem the download speed is naturally higher than I previously reported and the internet is working fine and seems fast enough it's just that compared to the other PC's on the same network this PC (Linux2) is showing significantly slower download speeds, I took the same average readings with the other 2 PC's and the averages are Linux1=43.00mb/s & Linux3=29.84mb/s

Well if it's currently working, probably best to leave alone for now then :)
