After we returned on Sunday from our trip to Hua Hinn, I found that our Internet service was having issues again. Finally, I got someone from True (the provider) to look at it today. My connection would intermittently go out, and when it was on, it was only 10% of the normal speed.
I'd reset the router dozens of times and rebooted just to make sure it wasn't something that I was doing. The technician saw the problem, and then plugged his own router into my connection and it performed normally. He told me that the problem was my router.
So I went over to Central and bought a new router. When I tried to install it, I had issues, not realizing that unlike the previous device which serves as both a modem and a router, the new one only acts as a router. Before I figured that out, I plugged the old one back in and it seemed to work just fine. Eventually I got the new one to work as well when I found another cable modem that I have from when we moved in.
The problem is that the return policies here in Thailand generally suck. Unlike a lot of places in the U.S. where you could return something you didn't need shortly after you buy it, here that is much more problematic. In other words, I probably own the new router for keeps. It is supposed to have a better range and has a couple of different wireless frequencies, so it's not all for naught.
