It all started with a Linksys WAG54G2. Most of the time it works well but sometimes the connection gets really slow (1-3Mbit/s, usually 10-13Mbit/s) or drops completely. When I talked to Linksys support, they told me to get it replaced. So I went back to the store and replaced it for a Linksys WAG120N. After a few weeks, the same problem comes back. I talked to the Linksys support and they told me to get it replaced again.
I have also talked with my ISP and they said that there was nothing wrong, "everything works", they said.
So now, I'm wondering if anyone got the same problem or even better, got a solution.
I installed the latest firmware on both devices. I noticed that the WAG120N got really hot so I turned of the wifi and got a d-link instead. There is also a fan that's pointed at the device in case it gets too hot.
For those of you that don’t know, the WAG54G2 and the WAG120N are a combined modem and router.
