MJCM Posted August 17, 2016 Share Posted August 17, 2016 Wow @johng Most people already would have given up, but you are persistent !! Link to comment Share on other sites More sharing options...
johng Posted August 17, 2016 Author Share Posted August 17, 2016 Most people already would have given up I'm just intrigued as to why it suddenly stopped working looks like something in my modem or router is stopping only firefox from fully functioning on Thaivisa this kind of makes sense as I had modem problems after a lightning storm just before this problem started.

MJCM Posted August 17, 2016 Share Posted August 17, 2016 Just now, johng said: user agent back to firefox Very strange that changing MTU to something else then standard prohibits Firefox to do something on a Website.

Thaivisa is the really the only forum I regularly post to most other sites I just read and haven't noticed anything sqiffy with them I could/can login to Gmail my wife can login to Facebook etc. Just now I tried Thaivisa firefox on my android phone ( WIFI ) and can't login get the same "connection was reset error" can read ok but not login !

MJCM Posted August 17, 2016 Share Posted August 17, 2016 Stupid question (sorry after all this time and you trying everything all ready) replace your router and see what it brings. Believe it or not, I have in total 4 routers - Router supplied by TOT (never used) - 2x ASUS Routers (where on sale at my local hardware store and are oke) - And my Main Router is Fortinet FWF30D (http://www.avfirewalls.com/FortiWiFi-30D.asp) So in case TOT tells me it's your router (when my Internet is down AGAIN) I tell them "I have 4 and tried them all" and that usually shuts them up Link to comment Share on other sites More sharing options...

johng Posted August 19, 2016 Author Share Posted August 19, 2016 http://www.dslreports.com/faq/695 Quote For PPPoE, your MaxMTU should be no more than 1492 to allow space for the 8 byte PPPoE "wrapper," but again, experiment to find the optimal value. For PPPoE, the stakes are high: if you get your MTU wrong, you may not just be sub-optimal, things like UPLOADING or web pages may stall or not work at all!

lungbing Posted August 24, 2016 Share Posted August 24, 2016 I've given up on Firefox for just this reason. I now use Vivaldi, and as a backup browser Cyberfox, but that only rarely. Link to comment Share on other sites More sharing options...
