I'm using CAT ADSL at several locations, and simply cannot post anything on TV.

Doesn't matter which PC or laptop I use, after I click add reply, it just sits there waiting until the time out screen comes up.

Using AIS GPRS, no problems at all!

Also on CAT, the pages never reach the "done" status when loading, but gets stuck on "waiting for www.google-analytics.com" for ages. Not sure whether taht is the cause of my posting problem...

I use CAT Telecom. Not a Problem. But, like you say, sometimes I must "wait for www.google-analytics.com" some 10 seconds.

Check your router.

May you try using a Proxy. And if you had QoS enabled in your Router, disable it and set MTU to 1436.

It's just a test but may helps.

Cheers.
