OK, now weirdness ensues. Just tried speedtest.net again and I'm getting 20mb/s!

So is what iwconfig reports wrong?

I've tried using speedtest.net, which gave me a speed of 5.98mb/s, so I'm believing iwconfig.

Running it on my phone gives ~20mb/s.

Unfortunately no difference.

I've tried changing to WPA2 and AES and it has made no difference, still stuck at 6mb/s.

Also tried the wireless at work, standing next to the AP I got a thundering 1mb/s...

I will give it a go tomorrow. I will also try connecting to the wireless at work and see if it is any different.

unfortunately that didn't make any difference to the speed, still stuck at 6mb/s. But i seem to have less gumpf in dmesg:


[ 10.753470] ath10k_pci 0000:02:00.0: pci irq msi-x interrupts 8...

Does the second command turn off power saving for the wifi card? I'm not great with sed, so does it just substitute 2 for 3 in effect?

I have the same wireless card in my ideapad 310 and I also have problems with disconnections and slow speeds. Currently I only get 6mb/s when my other laptop is showing 200+mb/s on the same network....

Yes it does actually, I found a usb stick with 13.04 on and that works.

I think I'll download 13.10 and give it a spin.

Thanks for the help.

Your wifi card may be under the keyboard, if there are no other removable panels on the back.

Thanks for that. The bios on this laptop is very limited in terms of configuration. Apart from enable/disable the wireless card there isn't anything to choose. One peculiarity of the bios is that...

Here you go:

The wireless works when I boot the machine into Windows 7, so I do not believe this is a hardware issue.

This happened after I attempted to upgrade from 12.04.1 to 12.04.4

I now have the...

Here we go:


lspci -nn
00:00.0 Host bridge [0600]: Advanced Micro Devices, Inc. [AMD/ATI] RS690 Host Bridge [1002:7910]
00:01.0 PCI bridge [0604]: Advanced Micro Devices, Inc. [AMD/ATI] RS690...

I will post the output from those three commands tomorrow, but the second only picks up the ethernet connection. lspci showed nothing related to the wireless but I didn't use -nn.

Thanks.

This issue seems to be a little different to the normal Boradcom wireless problem. I upgraded from 12.04.1 to 12.04.4 following these instructions:

Your network connection will also go wonky as the network card(s) in the new hardware will have different MAC addresses. for example eth1 will not work and a new eth2 will appear.

I assume you ran zenmap on the actual machine and not on a different machine on the same network. It may be that the ports which are open are internal facing and so not a problem.

Having a look through the log files should help shed some light on what's happening. I think auth.log will be the one you want to look at. Try connecting from outside your network and note down the...

You are given the option to choose the networking setup when going through the installation. I think the default is to use DHCP though.

Previously I have had a kernel update which cause similar issues. A subsequent update sorted it.

I found VirtualBox was easy to get up and running on the desktop version of 12.04, and I found it very useful in terms of being a beginner at virualisation.

@Sandyd, I hadn't come across Proxmox...

Bit of an oddball suggestion, but I had an old server which I had all kinds of random problems installing ubuntu server on which turned out to be due to the cd drive being full of dust and the lens...

I agree, I normally setup a new server as a VM on my test machine, making good notes of the setup/configuration, then once I am happy setup the live server. Also being able to clone a production VM...

I find the best thing about VMs is being able to create multpile copies and snapshots of specific VMs so that I can experiment and then roll back if (or more likely when) I hose one. Also by running...
