SOLVED: dual boot machine, loss of Net access under LMDE

Postby peyrol on Sat Aug 24, 2013 8:15 pm

I have a dual boot machine, LMDE up6 Mate amd64 and Windows 7 HP. With Windows, I can connect to the Net, browse, watch Hulu etc. For the past week, I have not been able to do so with my Linux Mint Debian, although it was working fine previously. I can ping my loopback address successfully, but not Google:

Code: Select all

Attached is a screen shot of my System monitor. Something is going on, at low speed, but I don't know what. I ran MintInstall, and I was able to view comments on a package, although it took a long time. I was unable to install any package, however.

What information can I provide that can help narrow down this problem? I notice another post "Strange Router problem" which complains about recent Net connectivity issues. It might be just a coincidence, but is it possible some recent package upgrade has caused this problem? Is there any way Windows could have sabotaged Linux, even though Linux is on a different partition which is not mounted when Windows is running? Or maybe my ISP is suddenly unfriendly to Linux? TIA

Linux Mint is funded by ads and donations.

Sometimes there are network devices that will not be properly re-initialized when you warm reboot from Windows to Linux. A cold (all the way off) reboot solves this problem

There may be another problem. Are you able to ping your router/gateway? What subnet mask does it use? I doubt it is 10.0.0.1/24. Your router most likely resides at 192.168.xyz.1 Your ping to 173.194.34.36 tells us that your NIC has an IP address of 10.0.0.1. I smell a configuration rat. Typically it would have a netmask something like 192.168.0.x or 192.168.1.x, etc

Your computer communicates with the internet by way of a router, all of which use trasmission control protocol. It is an International standard and there is no Linux vs Windows flavor. Your ISP is nearly certainly not your problem. It is also unlikely that Windows corrupted your Linux partition.

So, my IPv4 address is 10.1.252.148, my subnet mask is 255.255.252.0, and my default gateway is 10.1.252.4.

Do you see anything wrong with this configuration? Just to repeat, I can access the Net just fine under Windows.

I don't have a router device with me. My ethernet card is connected to a port in the wall. Turning off the computer completely and turning it on again does not solve the problem.

EDIT: Yes it did! My apologies, and thanks!
