I have an Asus RT-N12 hw B1 router with Toastman's tomato-K26-1.28.0500.5MIPSR2Toastman-RT-N-Std.trx . The other day while downloading a 4.4GB ISO file the other computers on the lan were unable to browse websites at all. Both Firefox and Chrome would time out on my 20Mbps/.5Mbps cable modem connection. I have downloaded ISOs on my prior DSL connection without having this problem but I was using a WRT54GL router then and did not have the timeout issues with other lan boxes. Just wondering whether there is a known problems with the above build being over whelmed with heavy traffic and if upgrading to the tomato-K26-1.28.0501.3MIPSR2Toastman-RT-N-Std.trx build would help at all? I assume if I do upgrade it can be upgraded over the top of my existing firmware?
