I.M.O., Belkins bite !! That router is not very highly rated. The NAT tables may be getting saturated and the powercycle operations clear them. Do you do P2P thru that router ? Maybe it isn't handling mutiple concurrent connections very well.. Are you using WEP or WPA wireless encryption ? I've read about major slowdowns with that unit if WEP is used. You could also try disabling the SPI firewall to see if that is causing it.
Here is what I received from Belkin. Does this sound correct?
The MTU size cannot be changed on the router if the router has been configured for cable/dynamic connection. However, the MTU size on the computer can be changed. The third party DRTCP software can be used to change the MTU setting. This can be downloaded from this link - http://www.dslreports.com/drtcp
- Download the file "DRTCP021.exe". - Unzip the Utility to your desktop. - Run the utility. - In the "Adapter Settings" drop down, select the ethernet driver and adapter used to connect with the network. - In the MTU box, type the MTU size as 1400. - Click in any other box, without changing the data there. - Click "Apply". - Click "Exit". - Restart computer.
I'm not sure why you want to change the MTU, but changing it on the PC should work fine. If the PC's MTU is 1400, the PC won't ever send anything bigger than 1400, and will request that servers send packets smaller than 1400 to it. It doesn't matter that the router's MTU is bigger, because packet sizes are negotiated by the end points.
There could be a problem if you set the PC's MTU higher than the router's, but that's not what's going on.
It looks like many, many other people have had issues with constant unexplained disconnects....although some do report no problems....perhaps it is a build quality and manufacturing QA problem...cheap parts put together shoddily? Some work, some don't....
I had the same problem that is listed elsewhere on this forum and on the Web. My Belkin Wireless N Router was slow. (Motorola Cable Modem => Belkin Wireless Router => direct connect to desktop). Using the wireless portion I could utilize full Cable bandwidth. Using the Ethernet cable I could only use 1/7 of the bandwidth. After changing the computer's network adapter from Full Duplex to Half Duplex the problem disappeared. I tried other settings but that seemed to be the one that created the problem. I would suggest that if others have this issue, please try setting to Half Duplex in the Control Panel-Network Connections-Local Area Connections-Properties-Configure-Advanced Tab. (Link Speed & Duplex)
Full Duplex was working for many years just fine with my old ADSL modem. I always received full bandwidth. But for some reason things changed with the cable modem.
So for what it is worth. Give it a try. Recycle all power and maybe it will fix your problem, too.
