Reset Wireless Adapter

Post by Graeme »

Hello Loungers.

I hope you're well.

I think this is a hardware problem but it might be a Windows 10 problem.

My trusty i7 Toshiba laptop is 6 years old and it has always performed very well. Just recently it has started loosing it's wireless connection after 10-15 minutes running. If I right click the wireless symbol (now a globe symbol) I can run the Windows Troubleshoot problems thing. This then tells me it's resetting the wireless adapter and fixes the problem. It returns the message Problems Found, The default gateway is not available - fixed. 10-15 minutes later the same happens only this time the Troubleshooter is unable to fix the problem and reports that the Ethernet cable is unplugged.

Anyone know of a fix or is it time for a new laptop?

Thanks

Regards

Graeme

This may be a problem with your WiFi access point, or your router, rather than with your laptop.
Do you have other devices connected to the same network? Do they work reliably?

Hello Stuart.

The problem seems to be only affecting my laptop. The bandwidth drops to 5-10Mb/s at times but there are two other PCs in the house, Netflix on the TV and my Android tablet, none have the same disconnection problem.

How old is your router?

Until recently, I had an old router, and while my laptop and smartphone didn't have problems connecting to it over WiFi, my desktop started losing the connection more and more frequently. A couple of months ago, my ISP informed me that my router was outdated and sent me a new one. The problems disappeared instantly, and haven't returned...

Hans

Hello Hans

We have had the router exactly 18 months because BT are nagging us to renew the contract! I can only assume it was new at the time.

Perhaps I'll set my phone as a hot spot and see what happens to rule out the router.

Thanks

18 months isn't old. I think mine was at least 10 year old...

Here's something you could try to see how it affects those symptoms next time. Run these commands in a command window, you will need to have admin privileges so start the command window by right-clicking a shortcut and choosing Run as Administrator...

After you run these commands please copy the output and paste it into a post here. You can put the output between [code] and [/code] tags to make it more manageable.

There you go Stuart.

Hope it means more to you than it does to me!

This was whilst I had functioning wireless.

Has the output been truncated? I was expecting to see that the WiFi connection had been re-established - but we only see the output for the first three Local Area connections.

Attempt#2 shows that your computer can talk to your router, which is also your default gateway, at IP address 192.168.1.254

I assume that everything was working properly when you issued this command.

Try it again next time you have a problem

Did you accidentally truncate the output from IPCONFIG /RENEW again? Or was there really no output from the Wireless adapter? If this is the case then it is definitely a hardware fault on the laptop.

Well, I would like to think not! But I wouldn't put it past me. I did notice that the text ended as before.

My wireless connection dropped out half way through that last sentence. So I have run all 3 commands again and I can confirm there was no more. This time though it times out right at the end.

This is significant. The PC can see the WiFi interface and talk to it, but the WiFi can't connect to the router. This would indeed cause the error message "WiFi" does not have a valid IP configuration.

I suspect that the problem may be with your router rather than with the PC
