I have been a fan of tomato ever since the original which i was running on a linksys wrt-54gl. I recently bought an asus rt-ac66u and installed shibby on it. I was very pleased and was flying along but noticed a problem. I would start the router up and connect to it. I'd connect at 702mb. Then after an hour 526.5, after another hour 373, after another hours 263, then 175, then 117, until it would just completely crap out and need the wireless radios reset. There was also one random dead spot in my apartment that my desktop worked fine at but my laptop could not get 1mb of throughput. I'd walk 3 steps to my right and boom 1mb would shoot up to 90.
I tried adjusting the channel, I tried adjusting the power, I made all sorts of changes to the router and the drivers installed on the desktop but nothing would fix it. I updated to the newest version of shibby which came out 2 weeks ago and hoped that would fix it, but the problem still exists. I tried erasing the nvram also, but that didn't fix it.
I flashed the router with the asus-wrt merlin firmware 48hrs ago and have had no problem since. The dead spot went away and the bandwidth stays at a solid 526.5-702mb from the farthest point in the apartment. I'm glad its working now, but I'm a little bummed tomato wont work. Asus-wrt merlin isn't as feature rich as tomato and it wont do some things that tomato does and although its working well, i feel like its missing something.
Let me know if anyone else has encountered this and if there is a known fix.
