Hmmm, I can see a pattern developing here. I started loosing it again. Changed back to MTU=1492, enabled, and it stays on. It seems changing MTU keeps it on for just over a week then it starts dropping again. What that means I''ve no idea.
Never go higher than 1492 MTU, or lower than 1472 MTU.
The theoretical maximum for an MTU setting is 1500, after that point packets start to fragment, including packets that let the ISP know you're still connecting to them. 1500 would be fine, except there's an 8 bit encapsulation value attached to all MTU levels. So if you set it at 1500, you hit 1508, and your packets are fragmenting.
Linksys told me to set it at 1500 and it worked ok for about 10 days then started dropping again. Changed back to 1492 and it works ok again for a similar period. Would setting it lower be worth a try or would its performance go down? Would lower = more stable? This has only started after upgrading the firmware.
Like I said I'm on 1.45 11, which was the newest firmware at the time. Just checked Linksys and there is a newer firmware. The guy did tell me there had been a few 'complaints' of the same thing. Does this look like they may have fixed it? I haven't installed it yet as I'm in the middle of three days off and redoing the bathroom, groan.

1492 + 8b encapsulation brings you right to 1500.
I still don't think MTU values are your problem.
I've no idea. Altering it does seem to make it stable for a while but....
