WiFi not connecting - possibly due to a Connection-specific DNS Suffix

I'm trying to connect to my work's wifi network, however my new accommodation seems to have set a "Connection-specific DNS Suffix", which I believe is stopping connections to other networks. Connection via ethernet is fine.

I'm running Windows 8.1 on a Dell Latitude E5550. Here's my ipconfig /all

Windows IP Configuration

   Host Name . . . . . . . . . . . . : Tim_Laptop
   Primary Dns Suffix  . . . . . . . :
   Node Type . . . . . . . . . . . . : Hybrid

   WINS Proxy Enabled. . . . . . . . : No

Wireless LAN adapter Local Area Connection* 3:

   Media State . . . . . . . . . . . : Media disconnected
   Connection-specific DNS Suffix  . :

   DHCP Enabled. . . . . . . . . . . : Yes
   Autoconfiguration Enabled . . . . : Yes

Wireless LAN adapter Wi-Fi:

Ethernet adapter Ethernet:

   Connection-specific DNS Suffix  . : home

Tunnel adapter Teredo Tunneling Pseudo-Interface:

   Media State . . . . . . . . . . . : Media disconnected
   Connection-specific DNS Suffix  . :
   Description . . . . . . . . . . . : Teredo Tunneling Pseudo-Interface

   DHCP Enabled. . . . . . . . . . . : No
   Autoconfiguration Enabled . . . . : Yes

It appears as though customer.blandford.derwent.lan is to do with my accomodation's network (ran by Ask4). I've tried running ipconfig /flushdns (both normally and as admin) however it still doesn't work. I've had a look around other forums, etc., but couldn't find anything that seemed to work. Has anyone got any ideas of what I can do?

Thanks in advance!

P.S. I'm not that familiar with troubleshooting network problems, so please bear with me & make any instructions clear.

"Connection-specific DNS Suffix" only affects DNS queries that don't specify the domain name, so shouldn't be a problem here. Try to set your DNS servers to Google Public DNS.

That seems to do the trick @harrymc, thanks for the advice! – Tim R – 2018-11-12T09:55:29.380

Very good. I added an answer which you might accept (tick the V). – harrymc – 2018-11-12T10:05:23.510
