I have recently discovered that I need QoS on my Linksys E1200v1 since Skype calls are unstable due to my local network. I have tried to install Tomato Shibby on it, and failed. Below is the full description of my actions. This forum does not yet allow me to post links in any direct or indirect form and for this reason I have not been able to indicate the sources of my info and my downloads. If these links are necessary, please indicate and I shall try to post them in my responses. According to Tomato by Shibby Router List, Linksys E1200v1 is supported by Tomato Shibby version K26RT-N. I downloaded releases 133 and 110 from Tomato by Shibby K26RT-N for Linksys E series download pages, filenames tomato-E1200v1-NVRAM64K-1.28.RT-N5x-MIPSR2-133-MiniIPv6.zip, tomato-E1200v1-NVRAM64K-1.28.RT-N5x-MIPSR2-133-Mini.zip, and tomato-E1200v1-NVRAM64K-1.28.RT-N5x-MIPSR2-110-Mini.bin I extracted the bin files from the zips. I did 30-30-30 reset on the router: pressed the reset button on its bottom with ballpoint pen for > 30 seconds, then unplugged the power supply cord from the router while still keeping the reset button pressed, and kept it pressed and unplugged it for another >30 seconds, then plugged the power supply while keeping the reset pressed, and kept it pressed for another >30 seconds. I waited for the router to come up and did Firmware Upgrade with one of the bin files. The router started upgrading but later reported "Upgrade failed". I waited for the router to come up again, did another 30-30-30 reset and tried Firmware Upgrade with another bin file, with the same result. I repeated the procedure (including 30-30-30) with the third bin file, with the same result. For some of the files, Upgrade failed was reported just after a few percent done while with others it progressed over 11%. After that I disconnected the second computer from the router (it was connected by a wire), checked that only one computer appeared in its DHCP table (the one from which I was trying upgrading it), and repeated the entire procedure with doing 30-30-30 for each of the three files. The result was the same. I would appreciate any help.
