SSHing to the Pi kills my internet connection!

Fri Nov 15, 2013 8:37 pm

I have my Pi connected to a Virgin Superhub, my W7 PC through a powerline adaptor to the superhub. If I SSH into the Pi with Putty, I can connect fine and use it for a while, but then my PC loses internet connection.

It has an IP address, renewing it, flushing dns, restarting DHCP client, disabling and enabling the adaptor dont do anything. Only a reboot of the superhub fixes it. Other devices on the network work fine.

Anyone seen this or have any ideas where the problem lies?

Is the RPi wired or WiFi?

What's in /etc/network/interfaces?
What's in /etc/wpa_supplicant/wpa_supplicant.conf

Are you letting your Virgin hub hand out a DHCP address to your RPi or are you trying to give it a fixed IP address?

Does your Win7 laptop have a DHCP address or a fixed IP address?
Open a windows command window and take a look with the 'ifconfig /all' command.

What else is on your network?

How many DHCP addresses are in the DHCP pool defined on your Virgin Superhub router/switch?
How long is the DHCP lease time?

My home LAN has addresses xxx.xxx.1.30 to xxx.xxx.1.70 defined in the DHCP pool (so forty devices before I get troubles).
Lease time is set to two and a half days. I've assigned static IP addresses to the things that are always ON (including my RPi).
