There's your clue the modem is in trouble. See if there is new firmware, keep the unit COOL and setup per the CNET Networking Forum advice.
Good luck and hope it's not one of those multiple issue problems. But for now you know that the modem is trouble.
My internet has been having a bit of trouble lately, and I'm trying to find out whether the problem is with my modem, or if it's with the network adapter in my computer.
Could somebody help me? I will post information as needed. The modem is a SmartAX MT882, and my adapter is a Realtek PCIe GBE.
Symptoms: Connection craps out and needs to reconnect often, especially when watching videos or trying to load too many pages at a time.
Getting less than maximum possible speed, as shown by the maximum dl bandwidth on the settings page of my modem. Sometimes I get up to speeds of 150 kilobytes/sec, but then modem needs to reboot and suddenly I'm limited to 60 kbps.
When I use 'Diagnose and Repair' I get the response "Cannot find DNS server" or something like that.
My OS is Vista Home Premium 32bit.
