I own a Linksys E1200v2 and flashed to get TomatoUSB Shibby 1.24 (and tried the last version, too)
Unfortunately, since I installed it, the Bandwitch Limiter automatically enables every…. yeah, it's quite random but it's about 1 to 4 days, to limit every computer in somewhat random priorities and random values (usually 1000, 2000 or 10000 kbps, sometimes 100 or 1) and random UDP/TCP limit (very low ones), it also happens that I can only access 1 computer to the router when it happens, the other ones blocks HTTP (because when it happens, I can call on Skype but I can't go on the web by web browser)
This option can be really fun for some use, but in my case it's more annoying than anything else…
No QoS enabled, default configuration, the only things I did is setting the WiFi with correct channel to optimize it, and enabled Wake on LAN (and opening port to a local computer for Wake on WAN, the only one connected by RJ45)
So…. what can I do?
Well, I think I gonna go back to the original firmware but I'll lose the WoL feature, that's not interesting, and maybe clear reset (30/30/30) but I don't know…. what you'll do?
