If it used to work, but now doesn't .. I'd assume one of 3 things

a) a driver update has broken things  <-- we've messed with this, so seems unlikely

b) interference from another wireless source  <-- unlikely if other PC's aren't affected

c) a hardware issue  <-- unlikely to be the router if it previously worked and continues to work on other PC's . so we're left with a failing wireless adapter in the PC
(it would be nice to prove this theory with a USB wireless card if you have one ?)

Thanks Mark,
It looks as if c) is the way to go.
Where can I purchase a USB wireless card ? Novatech ? ebay ?
I will have a look around meantime and see what I can find.

The USB adaptor arrived this morning, but the software disc is written in MS Windows (all 8 versions)
I found the number for  TP-Link but I can't speak to anyone as the lines are busy.
I can speak to someone (after a while) on the 0845 number but I am not willing to pay for that.
Any ideas how to get Linux drivers ?
Also I don't know where to disable the internal wireless card, any help please

take care
Don W

Have you tried just plugging it in (maybe rebooting)? Drivers hopefully should be in the Linux kernel already

Hi chemicalfan,
I have done a reboot and the internal led on the adapter flashes.
I also have a led light above the keyboard that indicates that the built in card is working.
Should I disconnect the internal card ? and how ?

take care
Don W
PS I think you're right and the adapter is working.

Plug the adapter in and post the output from:

and

sudo lshw -C network

You should be able to use the new one with the old one still enabled (it'll be wlan1 instead of wlan0). If you really want to disable, you can add the driver to the blacklist so it doesn't load

So is there a problem now ?

No need to remove the onboard card, but you can usually disable it either in the BIOS of via a keyboard combo, or via a physical switch somewhere on the laptop

Thanks Mark,
No problem as far as I can see. I have had a couple of days away and haven't logged in.
I will see what happens this week with it, it has worked ok during an intense online session and didn't drop out at all.
I will mark this solved if that is ok.

take care

Your topic Don so mark it however you like .. happy to hear the problem is solved :)

Can I ask you to confirm this is the one you bought:

and that it worked "out of the box"  ?

This info may help someone else in the future .. thanks.

Yes Mark,
That is the one I bought.  :D I just plugged it in to a USB port and it works. There is a Windows installation disk included that I didn't need.

I have just met another connection problem after logging in this morning.
I am writing this on the Windows machine as the connection on the Linux machine was 2% when I started and it was taking an age to connect to a site.
I never have a problem with this Windows machine, it never leaves the room here and sits next to the router. It has been plugged in overnight and shows 100% charge, as I am entering this the computer still shows fully charged.
The Linux machine is the one I take downstairs and I am having problems with. It too was plugged in overnight and the LED on the front indicated the battery was fully charged. I took it downstairs, plugged in to the mains and switched on. After logging on the battery condition read 86% and charging and the internet connection came on at 2%. I tried to log on here but after a couple of minutes I still didn't have a connection. I shut down and came back upstairs with it and logged on here to write this.
I have now switched the Linux computer on and logged in. It shows the battery adapter is online and charging (86%).
The internet bar shows nothing and when I hover the mouse over it it says
WiFi network connection 'VM 185937-2G 1' active: VM 185937-2G(3%)
The LED above the keyboard showing the internet connection is lit and the TP-LINK adaptor is flashing.
I can clean the computer out and start again as the only thing I needed was the photographs/videos from my grand-daughters wedding and that is safely done and dusted. I could in fact wait until June and put on Peppermint 6 if you wish (I could put it on now in fact as a sort of idiots try out. If I can work it anyone can)  ;)
EDIT I have started up the Linux machine again and logged in. The status bar showed  'VM 185937-2G 1' active: VM 185937-2G(2%). I left click on the bar and it shows the connections. The top one WiFi Networks (Realtek 82.11n NIC), I clicked on disconnect and the status bar jumped to 92%. Working fine now  ;)

Can you not physically turn off the internal realtek one with a hardware switch or key combo ?

What's the output from:
Code: [Select]
sudo lshw -C network
