unable to access Router setup page

Hi All

Windows 8.1 Pro 64bit
Internet Explorer 11
(Enhanced protection mode off)
Avast Browser Protection installed)

Enter routers address of 192.168.1.xxx

Displays waiting for connection, then page cannot be displayed, tested with laptop as well, same issue, (Laptop is running Avast 9.0.2008 as well)

For what it is worth, I’m not having any problems accessing my router
Windows 7 Pro, 64 bit. Avast 2014.9.0.2008 VD 131112-1
Internet Explorer 10
(Enhanced protection mode off)
AOS (4 modules) Enabled)

It may be the difference in OS, or in IE version, however suggest you could check:-
(a) That your router address is correct
(b) Disable all of the AOS modules in IE11

What version of Avast are you using?

Avast Free 9.0.2008

None of the machines on the network running Avast can contact the router, I triple checked the addy, short of calling at&t support or restarting it as yet I’ve done all I can do so far, including repair of Avast Free on all systems, didn’t make a difference. I might restart it soon to see if that helps any…but not sure if it will or not as yet

What brand & model is your router?
Is any of the PC’s using the router connected to it by ethernet cable, or are they all using wireless?

All Ethernet, At&t Netgear 7550N Gateway, did a repair on Avast on all systems, and so far seems to be working properly now…worked on this most of the day trying to figure out what was the exact cause, still don’t know fully, but so far it’s working
