I’ll have your command requests soon I’m having a nightmare the network keeps dropping out the desktop is freezing and now it wont recognise the flash drive I’m using to transfer the data, rebooting now won’t be long 
OK, run:
sudo gedit /etc/udev/rules.d/70-persistent-net.rules
now remove everything I’ve highlighted RED … and change what I’ve highlighted BLUE
PCI device 0x10ec:/sys/devices/pci0000:00/0000:00:09.0 (8139too)
SUBSYSTEM==“net”, ACTION==“add”, DRIVERS==“?", ATTR{address}==“00:e0:4c:39:22:53”, ATTR{dev_id}==“0x0”, ATTR{type}==“1”, KERNEL=="eth”, NAME=“eth0”

So it now reads:-
PCI device 0x10ec:/sys/devices/pci0000:00/0000:00:09.0 (8139too)
SUBSYSTEM==“net”, ACTION==“add”, DRIVERS==“?", ATTR{address}==“00:e0:4c:39:22:53”, ATTR{dev_id}==“0x0”, ATTR{type}==“1”, KERNEL=="eth”, NAME=“eth0”
PCI device 0x168c:/sys/devices/pci0000:00/0000:00:0f.0 (ath9k)
SUBSYSTEM==“net”, ACTION==“add”, DRIVERS==“?", ATTR{address}==“d8:5d:4c:f6:44:aa”, ATTR{dev_id}==“0x0”, ATTR{type}==“1”, KERNEL=="wlan”, NAME=“wlan0”
SAVE the file, and reboot.
Then send the output from
iwconfig

See above.
OK, this might be obvious, but have you tried to move the PC to the location of the PC with good connection?
Hi SeZo
OK, this might be obvious, but have you tried to move the PC to the location of the PC with good connection?
No we haven’t tried that I’m hoping that will be a last resort but but I agree sometimes the obvious turns out to be the answer
OK it’s now connecting to the internet

And the speed ?
And the speed ?
Dare I say it worse than ever
Download = 0.388 mb/s
Upload = 1.63 mb/s
OK, I think SeZo is right … we need to at least test this PC somewhere else in the house … preferably where you KNOW works
Ok I’ll hook it up to where Linux3 is and try it there
Watch this space
Just leve enough gap for air flow 
Ouch … Hahahaha
Ok I hooked it up to where linux3 is situated at the other side of the room if anything it’s worse I done 1 speed check then tried another and it wont connect to the site but I can safely say it’s no better
I think I’m just being a PITA with this now, maybe I’m expecting too much from old crap hardware
What do you think ?
This could be a long shot, but worth to try. Switch off all other equipment connecting to your Super Hub Wirelessly.
Try it with just the problem PC. See if you get any better results.
There’s only 1 other device connected wirelessly which is this PC (Linux3) everything else is connected by ethernet ie 3 xboxes and a NAS box running freenas
But I’ll give it a shot
I’m also beginning to think this is another hardware issue, and not wireless at all
Possibly screwy interrupts ?
Another long shot … Is there a BIOS option to reset the “DMI pool data” or similar
And is the BIOS set to “Plug and Play OS” ?
I’ve been through all the bios menus and I see nothing about plug/play or DMI
Sorry 
One last thing … try:
sudo modprobe -r ath9k
then
sudo modprobe ath9k nohwcrypt=1
any improvement ?
Sorry Mark no improvement it’s back not connecting to the internet, I think the best thing we can do for this useless pile of junk is give it a decent burial preferably from a great height
