Hi,
I Also have This Same Problem
But After A Few Tweaks I Get It Working Again
This Works For Sky Idk About Anything Else.
Basically Like 3 Months Ago My Internet Was Not Working There Was An Orange Light On The Router
Which Is Limited Access
I First Thought It Was An Outage In My Area Because Thats What I Read On The Sky Address
Go To The Start Menu And Type Cmd Or Windows Button And R And Type Cmd In The Run Box.
Then Write "ipconfig" Something Like This Will Come Up
Find Default Gateway And Look Next To It And An Ip Will be There For Example Mine Is "192.168.0.1" Then Go To Your Browser (This May Not Work For Others But Worked For Google Chrome) And Type That Ip In
And Press Enter, An Authentication Box Will Appear You May Need To Find This Out On You Broadband Providers Website But For Sky It Is Mainly
Username: Admin
Password: Sky
This Screen Will Pop Up
Go To Setup
And There Will Be Some Options
( I Cant Show You As This Contains Personal Information)
And Then Go To Channel And Change It To Something Random But try To Avoid The Same As People In Your Local Place
Such As Neighbors. This Causes Interference
Press Apply And You Will Lose Your Internet Connection As It Configures Everything But It Should Come Back In A Few Seconds And Hopefully Your Internet Connection Should Work.
Hope This Helps
