I experience some problems while trying to upload (to ftp) a big (50Mb) file. After some time my linksys router seems to disconnect the connection. I called the linksys helpdesk but they were not able to help me and advised me to return my router, they thought it was a hardware problem. I changed the router and got a new one but I still have the same problems! I experience this problem either when I'm connected wireless and wired. Anybody has a clue? The salesman told me it is a known problem for some older routers from linksys. I hope someone can help me out. Thanks in advance!
