Problems since switching ISP from Virgin to TalkTalk (UK)

Question

Just switched from Virgin to TalkTalk and now having following issues when connected via Orbi:
- Cisco AnyConnect VPN won't connect
- random 404 errors on some web pages
- Can't download iOS apps
&nbsp;
All work fine when connected to TalkTalk wifi so must be an Orbi or Orbi to TalkTalk router problem.
&nbsp;
Any and all ideas welcome.

What FW is currently loaded?What is the Mfr and model# of the ISP modem the NG router is connected too? Modem Combo Units:Couple of options,1. Configure the modem for transparent bridge mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router.

Sorry, should have been clear:&nbsp; ISP changed but also router (comes with the package).&nbsp; Virgin was cable, new router is ADSL.

Also it looks like the&nbsp;Sagemcom FAST 5364 v 3.00 is a Modem/router combo which requires special setup to work with the ORBI ROUTER.

Thanks for that.&nbsp; How did you discover this / any idea where I can go to find out what is required?&nbsp; TalkTalk are being less than helpful :-(

Looks like you may need to set the Orbi in the AP mode.&nbsp; Many here on this forum can help with that.&nbsp; The Orbi manual should also provide guidance.

If you can turn OFF items like uPnP, firewall and wifi on the modem, set up a reservation for the Orbi router on the modem, this could help. if not, I presume AP mode will be the best solution. This seems to be a limiting issue with the modem. Too bad DMZ isn't available on the modem.
Have a great evening.

Does the sagecom modem/router have a DMZ?

Looks like Option 3 is the only one from your list that I can get going, though it makes no difference.

Don't think so.&nbsp; All looks pretty standard in terms of network settings (DNS, DHCP, routing etc.).&nbsp; I've now established that there's definitely no modem-only mode on the Sagemcom so I might have a go at turning most of the network features/settings off manually and using a static IP on the NG router.&nbsp; Or do the AP-only thing mentioned above.&nbsp; But all of that can wait until tomorrow.
&nbsp;
Thanks for all the responses so far - much appreciated.

Perhaps not.
&nbsp;
The only thing that you changed is your ISP (TalkTalk).&nbsp; Start there.
