Issues with VPN

[JSCL24]

Hi i'm having the same issues as many others with connecting a work VPN like https://community.talktalk.co.uk/t5/Broadband/VPN-issue/m-p/2923183#M844992

I have changed laptops, restarted the router, removed everything else from the network, separated SSIDs, held IP addresses, everything - any time I connect the VPN, it almost stops the internet and laptop running simple tasks but can still access websites. 

Was on the phone to TalkTalk support but they hung up!

OK thanks. The only known VPN issue is with the 136 firmware for a small number of customers, the alternative firmware nearly always resolves the issue so I'm not sure why you are still experiencing problems. Which VPN client are you using?

@Chris-TalkTalk it's absolutely infuritating, in the past hour it has crashed my computer twice, it is definitely a TalkTalk issue as it does not happen through other ISPs or tethering from mobile devices

Hi Chris certain elements of the VPN work, but others are blocked. What it does is crash the performance of basic Windows functions, File Explorer, Outlook, etc. It seems to think there are conflicting computers too, which is impossible. What is odd is as per my edited reply below, that I cannot get on the router website when the VPN is running. Something on the router/ISP is blocking certain actions.

So when you connect to the VPN, you are able to connect but it's just running slowly?

It's exactly the same - I cannot get on to the router's website itself with the VPN running

[Chris-TalkTalk]

Does there appear to be any difference following the firmware update or does appear to be exactly the same?

Hi @Debbie-TalkTalk I've done this now and the issue remains that certain parts of the VPN network are not accessible.

Hi JSCL24

Yes, please can you power down the router for a full 30 minutes and then retest?

[JSCL24]

Hi @Debbie-TalkTalk yes i'm still experiencing the issue - though I haven't restarted my router - should I?

[Debbie-TalkTalk]

Hi JSCL24

I can see that your router firmware has been updated. Are you still experiencing this issue?

Thanks

Debbie

Yes, that does have issues with certain VPN clients, most notably the Windows 10/11 inbuilt VPN clients. The TalkTalk support can offer you an alternative version that should work fine. I will ask them to do this for you when they return after the weekend.

I have a Sagecom Wifi Hub

Software version SG4K100136

Thanks for starting your own topic. Can you just advise which router you have and which software version it is running? Subject to that the support team will pick this up as soon as they can when they are back online from Monday.
