Hi UPC community,
I’m having problems connecting to my work VPN through the UPC connectbox.
All other devices on my network are ok and my personal VPN maintains connection without any problems. So far I have replaced my connectbox, reinstalled wireless network drivers on my work laptop, then finally replaced my work laptop. Everything I’ve tried seems to work for a couple of days, then starts to encounter problems. I am also able to connect to the work VPN via my connectbox, using my phone as a hotspot, but I would prefer not to have to do this.
Are there any connectbox settings that could be causing the problem?
Thanks for your help
John

Please send us your customer number, address and date of birth via private message. We will be happy to check the configuration of your modem.

johnydee99 From my experience, some VPN servers do not like IPv6 DS Lite. That’s why I have now changed your modem to IPv4. The conversion is done in 30 minutes. After that restart your modem. If you have difficulties, perform a modem reset. Press the reset button on the back of the modem gently with a pointed object for at least 25 seconds.

Please try again afterwards.

Greetings
Daniele

Thanks Daniele!
I will let you know if it works

johnydee99

Ok, it seems to be ok, I’ll reply again on this thread if I have any more problems

Thanks again for your help 🙂

Hi Daniele,
So I ran my router for a few days without performing a reset and VPN connectivity was better, but my wifi dropped out a lot for approx 1 min at a time, then returned. This seemed to happen at random throughout the day. Today I performed a reset and my VPN connectivity issues seem to be back. Will the reset have rolled back my router setting to IPV6?
I’m now back to hotspotting through my phone which is not ideal.
Is there anything else we can check at this end?
Thanks and regards
John

johnydee99 It is very strange that your modem has switched back to IPv6 after a reset. This should not be the case.

For this reason I changed your modem again to IPv4. The changeover is completed in about 30 minutes.

As for your WIFI - you could extend it with boosters or a mesh system so that the interruptions disappear.

Good morning Daniele,
Thanks for the updates, today connectivity has been good so far. 🙂
Do I need to perform a router restart?
Last week, I’m not sure signal strength was the issue; my laptop is in the same room as my router and the drop outs were experienced on all devices.
I’ll monitor today and let you know if there are further problems:
Thanks and regards
John

johnydee99 Your modem has been switched to IPv4. So you don’t have to do a reset.

Hello Daniele,
This afternoon this problem has re-appeared…. Is it possible my router has been switched back to V6 again?
Thanks and regards
John

Daniele_Sunrise

johnydee99 No this is not possible. Only we can make the switch back to IPv6 in the system.

Your modem is still on IPv4. Restart your modem once. After that please all switches and hubs / routers too.

Greetings
Daniele

Hi Daniele, thanks, that worked 🙂

Hi Daniele,
Unfortunately I’m having the same problems again this morning
I’ve restarted my router and done a reset, but my work VPN will not connect. All other devices on my network are connected without any problems
Is there anything else you are able to check?
Thanks and regards
John

johnydee99 We still don’t see anything that can explain the VPN malfunction. Please contact the VPN provider. We also had a short interruption of the VPN in the company today.

In addition, I recommend you to connect your computer via LAN cable as a test and to test the VPN again. I don’t see any devices that are connected via LAN.

Greetings
Daniele

johnydee99

Ok, thanks for checking
I just tried connecting via LAN cable and I get the same result, “No Internet”

Daniele_Sunrise

johnydee99 When you plug in the LAN cable, you may have to force a new IP with the CMD command “ipconfig /renew”.

If this is too complicated for you, plug in the LAN cable and restart your computer.

I’ll check with our IT again. Is there nothing else that could be causing this at the UPC end?

johnydee99

Ok, something just changed and the LAN and wifi are now both allowing the VPN connection.
I’ve no idea what happened, but it seems to be good for now
Thanks for your time

johnydee99

Ok, that is strange
I’m connected via LAN, but ipconfig /renew returns this:
