4GEE Home Router 3 - network clients browsing intermittent

essexboyracer — Tue, 26 Jul 2022 09:37:41 GMT

Business customer. We have 13 Desktop PC's connected to a domain controller running through a firewall and the into the 4gEE Home Router 3. Apart from the Home Router, this setup worked flawlessly in a previous office on a leased line, but since moving we've had to use 4GEE as a temporary stop gap solution till a new leased line gets installed. So the only thing that has altered on our network is the 4GEE Home Router 3.

Problem: All 13 network clients (Win 10 Pro) machines have issues getting to "some" websites and the problem seems worse with websites that require some sort of login (form submission). Their browsers (whether Edge/Chrome/Firefox) will just timeout or instantly display a check your connection message. Running speedtest.net throughout the day doesn't point to a signal issue with the EE router itself as it consistently gets in the 30 to 50gb range, upload speeds also seem ok at around half that.

Our external IT note that logging into the server (domain controller) is fast and doesn't show any issues in connection quality. Though logging into a client machine via teamviewer on the network is slow, almost laggy/jittery (Cat6 cabling throughout). It's as though there is some sort of DNS problem occuring.

What I've tried: Seen various topics of similar ilk on this forum and tried the following:

Disabling IPV6 on the network adaptor (believing the problem is with IPV6)
Setting Automatic Metric on the network adaptor (advanced settings) to 1 - https://airvpn.org/forums/topic/22650-windows-10-creator-update-airvpn-dns-slow/?do=findComment&comment=61284
Disabling QUIC (http/3) in Chrome - https://www.reddit.com/r/ipv6/comments/f41prj/google_sites_very_slow_to_load_when_using_ipv6/
Changing MTU - https://superuser.com/questions/633846/some-sites-extremely-slow-how-to-determine-if-its-ipv6-and-disable-it

What I haven't yet tried:

Connect a non-windows machine, e.g. a linux client to the network
Disable SmartNameResolution as referenced in https://airvpn.org/forums/topic/22650-windows-10-creator-update-airvpn-dns-slow/?do=findComment&comment=61308
ipconfig /flushdns
Trying to connect to the Home Router directly through one of the ETH interfaces (or wirelessly) therefore taking our network out of the equation.

Anyone other customers had similar issues?

Hi @essexboyracer,

Are you able to try accessing the problem websites using a phone or tablet connected to your router?

Do you see the same issue?

Hi @James_B

I'm not in the office today, but plan to go in tomorrow and try a few things, that being one of them. It doesn't appear to be signal strength as an employee on EE used his phone to hotspot a laptop and access a problem website fine.
