Until, that is, about two or three minutes after my NIC connects to my LAN. Then the transmission speeds (for all outbound connections whether local or over the web) slow to a crawl. When scp'ing, the file transfer stalls. When accessing a webpage, the transfer stalls and may not complete even if left for several minutes. This occurs with both wireless and wired connections.
The bizarre part is this: when I right-click the network manager and reconnect to the network, the problem goes away, but only briefly until the problem again occurs, requiring another disconnect/reconnect cycle on the NIC.
So, my friends, I'm trapped in a sort of linux hell, where my services are perfectly configured and everything runs beautifully, except that my network connections require a manual fix every 2-3 minutes. Please help? Additional info is attached.
Here are some bullet point facts:
- - This occurs on both wired and wireless connections
- The ONLY change in software/configuration change across the whole network was switching this computer from W7 to Mint 9
- This machine had NO problems with networking (on the same network) while running W7
- I have a server running Ubuntu Server 9.10, and it has not had any (networking) problems on this network.
- Network connections work fine for a (very) short period after boot-up (or any ifup'ing in general)
