PC not connecting to internet

Badger1970 · 16 Oct 2018 at 09:46

Hi

I'm using a BT homehub 5 router which shows a blue light and wifi is working from it. However, my pc which is directly connected to the router won't work.

The error message i get is "DNS_PROBE_FINISHED_NO_INTERNET"

Any ideas whats going on?
Thanks

Do you have any static IP or DNS set on the interface?

Are mobile devices able to connect to the internet via the router?

Hi, everthing connected to router via wifi works and powerline adapters are also working.

Tried various googled solutions below

Reset WINSOCK entries to installation defaults:

netsh winsock reset catalog
Reset TCP/IP stack to installation defaults:

netsh int ip reset reset.log
Reset Firewall to installation defaults:

netsh advfirewall reset
Flush DNS resolver cache:

ipconfig /flushdns
Renew DNS client registration and refresh DHCP leases:

ipconfig /registerdns
Flush routing tabl

But no luck.
Cheers

its not something as simple as a faulty cable is it, have you got another to try

Make sure you plugged it into the correct internet slot and not the lan one on the back of your pc

Hi
Last night i swapped over a tplink Archer 2800 as no lights were coming on so i thought it had it. Plugged in the old BT router and everything worked straight away. So cabling is ok. Try to connect to the internet this morning and now there's nothing.

Try connecting directly to the router, not through powerline. Move your pc next to the router.

Hi,
The PC is next to the router and directly connected.

Hold windows flag key on keyboard and press R.

Type cmd

Then in that black window that appears type, ipconfig /all

Paste the output here.

Hi

Tried my Tplink Archer 2800.... nothing happening. Plugged the BT and everything has started working! Bizarre

Is there any benefit in buying a NIC card in case this happens again?

Thx for all the help

Restarted pc to load some software and back to no internet connection. I've ordered A NIC card and hopefully that will sort the problem.

OK, i've resolved this in case anyone else has the same issue

1. Go to network connections and right click on the ethernet port being used. Select properties.
2. Select Internet Protocol Version 4 (TCP/IPv4). Select properties.
3. Select Use the following IP address.

In command prompt type IP config and use details to fill in the IPv4 address and the Subnet mask

4. Select Use the following DNS server addresses

Here i entered Googles DNS ones

5. Save

On saving the PC then recognised that DCHP was not on and fixed it.

Hope this helps
Cheers.
