Archer C7 - Blocking Various Websites
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
- Various sites are blocked by the router.
- I can connect to the sites if I plug directly into the modem, no problem or tethered to my phone so it's not a problem with the laptop/Mac settings.
- Tried this on 2 PCs and 1 Mac - same issues on them all.
- Here is what I've also tried: upgraded firmware to latest version, full factory reset, disabled firewall in router settings, disabled all VPN options in router settings, disabled all ALG options in router settings.
- Also tried flushing DNS on computer, using Google public DNS settings (etc) - but as noted it's not an issue with the PC and IP/DNS because it works fine plugged into the Modem directly.
Any other thoughts or things I should try?
Thanks for the ideas. Not sure what you mean by Network Topology but if it's structure, it's modem > archer c7 via ethernet. ISP is Start.ca.
Here are two examples of pages that wouldn't load yesterday:
Although the latter is now working today - literally couldn't get it to load once while connected to the router yesterday!
I tried various devices (2 x PCs, 1 x Mac) and browsers. As noted, once I connect directly to the modem, I can access these pages (on all devices), as I can when tethered to my phone - so I know it's not something related to the devices that is specifically a problem and it seems something related to the router itself is somehow blocking them. FYI - connected to the router by LAN doesn't work either (even though connected to the modem with the same LAN connection does work) - so it's not just a Wifi issue.
No parental controls on the router. I went through every single setting that could possibly be blocking anything (firewalls, VPNs - every router setting) and turned off anything that could be blocking it.
I tried the MTU at 1400 and 1440 with no luck.
Here's what happens when I ping a site that doesn't work (eg. speedtest):
