5g Broadband unable to connect to some sites

Grimwald — Fri, 02 Feb 2024 09:42:26 GMT

Since yesterday I have found that I am unable to connect to some websites and apps unless I use a VPN. I am also unable to connect to my works VPN or remote server but things like MS Teams and Outlook are fine. I have tried different things even a factory reset but still no luck.
I notice that the firmware of the NR5103E has been updated recently to V1.00(ACBJ.0)b15 and am wondering if this has messed things up as I see others have had problems with that. Is there anyway to downgrade it?

I'm also seeing this issue - some sites/apps are not working, and my work VPN is also not working.

hi, i'm using a mobile on 4G and i have what seems to be the same problem since some time last night. switching to 3G got things working again. i have a 5G phone and service in my area but not using right now and can't test. i had tried other things that i'd read, such as changing APN settings. an example site that's not working is ISPreview

Having the same issues since about 4pm Thu 1st Feb 24. Some sites are initially slow to load, others refuse to with a 'site took too long to respond' error (for example wikipedia.org)

DNS is working as the domain names resolve.

All devices connected to the router are affected.

Same here - and it is intermittent. A site that didn't work a few hours ago is now working. Switched to Google DNS servers and seeing the same. Looks like a routing issue to me ...

It was about 4pm yesterday for me. I have been on the phone and they made some changes to my router, no idea what, and I tested it and I could connect to the websites and works VPN however they said I then needed to reset the router and nothing connects again. They say they are going to phone back later.

Same here, from sometime early yesterday afternoon also using NR5103E. I may have fixed it for now by changing the the Cellular WAN from "IPv4" to "IPv4 IPv6 DualStack" in the Broadband tab of the router settings and restarting the router.

All sites that were previously inaccessible are now accessible, I've not tried my work VPN yet as I'm on annual leave today.

Just confirming that I'm also using an NR5103E, that my firmware recently updated to V1.00(ACBJ.0)b15, and that I've also been seeing this issue since early yesterday afternoon.

My Cellular WAN setting is already on "IPv4 IPv6 DualStack" - but one thing I've noticed is that after a restart, things seem work fine for about 15-20 minutes, and then the routing seems to break again after that.

OK not sure what's happened but everything is working again.

Having the same issue since yesterday morning, but H112-370 router with 10.0.3.1(H330SP51C21) firmware.

I'm also a 3 mobile customer so I've tried swapping my SIMs around. The issues are the same when using my phone SIM in the router, and I have no problem accessing any site on my phone with 5G using either SIM. I haven't had time to contact 3 support yet.

-edit-

The problem seems to have resolved while I was typing this😆 Hopefully it lasts!

11:45am, can now access the sites I was having issues with.

Resolved for me too since around 11:45 - fingers crossed that's it!

I found changing the APN from "3internet" to "three.co.uk" worked for me.

Seems to be fixed now - OK for the last few hours.

Since they fixed the problem I have noticed my speed has dropped significantly from around 850Mbps to less than 150Mbps. Anyone else notice this?

Re: 5g Broadband unable to connect to some sites

Grimwald — Sun, 04 Feb 2024 10:12:24 GMT

Interesting I changed the APN to three.co.uk as Spud had mentioned and got 850Mbps. Changed it back to 3internet and it went back down to under 150Mbps

I'm seeing vastly reduced speeds as well on 3internet APN. I'll try three.co.uk to see if it improves
