For the past several years I have had Verizon DSL in my home. Devices in use on network are Win7 Pro desktop, older Mac laptop with OSX 10.6.8, an ipad, an apple tv, occasionally an iphone. All devices worked just fine. Apple devices connect via WiFi of course; the desktop was hardwired via ethernet.
I got Comcast/Xfinity "performance" internet this past week (rated 25Mbps) with an Arris TG1682G modem/wireless gateway and am having a strange problem. No problems with any of the Apple devices. On the macbook, firefox 48 (the highest available for 10.6.8) works perfectly. On the Win7 desktop, the current version of Firefox that was installed had issues….some webpages load fine, others are scrambled. Sometimes they show up as garbled text/html. Sometimes they show, but the photos are missing or scrambled (look like corrupted jpg's). Sometimes top part of page looks fine, but as you scroll down, the lower portions turn into scrambled text/html code. Sometimes they don't display at all, but show a message about either an encoding error, or an SSL error.
The desktop was connected via ethernet cable. I tried disconnecting it and instead connecting via WiFI. It made no difference.
I tried uninstalling firefox completely (deleting caches, profiles, etc) and reinstalling. Same problems occur. I tried downloading an older version of Firefox (32). Same problems. I tried downloading the current version of Chrome. Chrome didn't work either….some pages fine, others scrambled, same as Firefox. Then I launched IE (which I typically never use)….whichever old version that came installed originally with Win7 Pro a few years ago when I bought the machine….and guess what? All webpages display just fine through IE.
And so I am truly puzzled. Can anyone think of any setting, or any reason WHY this might be happening? If IE can display sites fine, then why can't Firefox/Chrome? What setting could possibly be different between IE and other browsers? And because IE works, it can't be a network setting in windows, or some setting in the modem/gateway, right??
One more interesting point. Speedtest.net runs just fine through Firefox on the Macbook. On the PC, in ANY browser, it completes the download test and then just craps out…it never gets to the upload test. BUT…if I disconnect from the comcast/xfinity service, and connect to the old verizon DSL (I didn't cancel it yet), then speedtest.net works just fine on the Win7 desktop in all browsers (and all webpages load fine also, just like they always did, just very slowly).
WTF??? Any help much appreciated.
