Network connection issues

rmcellig · 2014-06-19 21:39:13

For some reason, my HP DV6 laptop is telling me that I have a wired connection but I can't seem to connect to anything. I tried connecting to my hosting server with Filezilla. Doesn't connect. I can't connect to any websites either and when I ping a site like cnn, it doesn't work.

At the moment my network is working on this laptop but sometimes I go to any website and it can't resolve the host. The other computers on my LAN are working fine.

Any ideas what I should do?

This is my ifconfig output:

Sounds like a DNS issue. If you can't ping cnn.com, can you ping 157.166.226.25? or google.com (74.125.226.105)

rmcellig · 2014-06-19 21:57:44

Pinging Google worked but. I think it does sound like a DNS issue. Should I change my DNS servers to something else? Should I useIPv4 or IPv6? What DNS settings should I try?

Any other CLI tools I should use to test?

Thanks for the help!!

Copper0 · 2014-06-19 23:37:28

Did it work by name or ip? You are setup for IPv4. Don't worry about IPv6 stuff for now that is still years away from widespread use.

rmcellig · 2014-06-20 00:03:47

By name. When I typed ping www.google.com, it worked.

Copper0 · 2014-06-20 20:24:17

OK I'm confused now. If you can ping google.com it is not a DNS issue. Well maybe an intermittent issue. What is your router? You may have something like parental controls or maybe a proxy enabled?

cat /etc/resolv.conf

will show you your which DNS you are using but I am assuming you are using DHCP and if the other comps on you network are working then this should not be an issue.

rmcellig · 2014-06-20 20:34:13

I am using DHCP. I'm using the router that came with the TV service I have. So far the connection has been working OK.

I started having network problems again. My icon in tint2 says network disconnected. I have linuxlite 2.0 in another partition with the same result. Funny thing is when I boot into my windows 7 partition, everything is fine. I booted from my puppy Linux 5.2.8 CD and network connection is fine as well.

For some reason I cannot connect to the internet anymore. All computers on my LAN work fine as far as connecting to the internet goes. All have a wired connection to the router. My laptop that does not workis a HP DV6. I have Windows 7 (NTFS), Crunchbang (ext4) and Linux lite 2.0 (ext4) installed on seperate partitions.
Windows 7 has no problem connecting to the internet. If I boot from my Puppy Linux 5.2.8 DVD, I can connect to the internet after using the Simple Network tool that comes with Puppy.

I am very close to reformatting my entire computer and starting over again. I hope someone can help me figure out what is going on. A million thanks up front!!!

At the moment, I am sending this post while booted into Puppy Linux from DVD.

Here is what I have done so far:

1. Tried different ethernet cables. Didn't work.
2. Tried connecting directly to my router. Didn't work.
3. Turned the router on/off. Didn't work

Here are the commands I tried as well which may shed some light on the problem. Please let me know if there are any other commands I should try.

Can't help you out directly, but you might want to pm one of the mods and get this thread moved to the help section where it might get more traffic. I can see where the solution is going to be some simple editing that another user has had to do.
