linux Strange internet problems

[Kronos]

So I can't quite place what the problem is. But the internet has connectivity problems.

Ubuntu 12.04

It only seems to be a browser problem, but isn't just firefox. I installed chromium and had the same exact problems. When I go to a webpage it takes absolutely forever with the little spinning circle in the top. The message at the bottom usually pends at waiting on www.webpage.com, then it will fail and get the problem loading page. Says the connection to the server was reset while the page was loading. I have to hit try again multiple times before the page actually loads. I've reinstalled firefox and tried chromium and have the same issues. It didn't do this when I first loaded the OS. While messing with the graphics card drivers in my previous thread is when I noticed it first happening.

Could it be an issue with the wireless driver (is that a thing?) that happened when I was installing and reinstalling the graphics card driver?

No idea, but I don't think it is caused by the graphics driver

 

Check if you lose packets, with mtr or something like that. Check the quality of signal, and wireless settings.

Are downloads slow, as well? Or it's slow only when you connect somewhere, then it downloads the page at normal speed?

Downloads are fine, steaming is also fine. It seems to be just at first connecting to the page. For instance when I link to youtube the page usually loads fine, but the video takes forever to start, but as soon as it starts it buffers just like it normally would by buffering faster than the playback. It's not rubberbanding or anything like it buffered the whole thing before it started.

 

I don't know much about checking packet loss, or what is acceptable values. Just pinging different ips I get occasional packet loss, 1-14%.

if you have the latest ubuntu, and firefox/chrome, by default you should not have those issues. how much free memory you have from it?

 

type the command

 

free

 

from the command line and see how much memory you had detected using your kernel... There could be lot of causes why, so just checking one by one.

What does your /etc/resolv.conf says? Have you tried changing them to google DNS yet and see the improvement?

[SunLight]

if you have problems only connecting it could be your dns

 

for the packet loss check I use mtr, if you don't have it you must install it, it's a little command taking no space and useful too, so install it if you don't have it.

 

I don't know what is acceptable, I tried

$ mtr www.google.com

and I had 0 lost packets in all hops after 50+ iterations, so I guess 0 packets lost would be the best, but I don't use wireless...

nameserver 127.0.0.1

search hsd1.wa.comcast.net

 

mtr gives me 0 packet loss through most of it. But right after my router ip address (10.0.0.1) there is a line that is unknown (???) with 100% loss every time no matter which address I use. Is that normal?

[PiNoY]

Have you try to edit your resolv.conf to include Google DNS in a single line like

 

nameserver 8.8.8.8

 

Ofcourse, make a backup before any changes. No need to restart system but restart all opened browsers and see if that would improve your browsing experience then.

I'd recommend a simple problem fix of turning off all your Internet devices. Disable it on your computer, and router for around 5 minutes. Should reset everything if it still doesn't load properly atleast you know that's not the problem.

[SunLight]

some machines could block the traffic generated by mtr or just don't reply, so I think it's normal. After all if it was 100% real loss you couldn't get to the following nodes.

 

have you tried another dns like google dns or opendns?

[Kronos]

Ok so sorry about the long gap. I was testing something out. It seems to be on the internet side and not my computer. Or at least to an extent. At my dads house the internet is completely fine with no problems whatsoever. However at my moms I have this problem. But it seems to be limited only to me. None of the other computers or devices have this problem connected to the same network. Does that narrow anything down?

Also a problem is submitting posts on this forum. I have to hit post and then the little loading bar in the top middle of the screen times out and keep submitting the post until it goes through.

Try disabling all firefox addons and restart Firefox to see if that fixed the issue. If you can uninstall Firefox and re-install that again to see if that would help also.

[SunLight]

I think you have some packet loss or similar problem. Are you the only one using wireless? When you say you have the issue and others don't, are they using wireless as well? Have you tried to change channel or other wireless settings?

 

Maybe using some tool like wireshark you could see what's going on, but maybe that's overcomplicated.

 

Have you changed the dns? (but at this point I'm not sure it is a dns thing)

[rolf]

Do you have wireless or a cable?

If cable, your cable might be damaged somehow.

If wireless, someone in your neighbourhood might be blocking you out. If you're at home, see whether there is someone with a better connection than you have (more bars as in Windows/cellphones), or try sitting next to the router. In that case, either configure your router differently or get a new one for overkilling that guy.

 

Simple (standard) verifications/solutions:

- Reset the router and/or modem, even try to set it off a longer time (night or so),

- Ping for a _long_ time www.google.com (10 minutes or so, "ping www.google.com" in the commandline. See if it breaks down. Especially notice if it will start with "could not resolve hostname.... a couple of times and only after that get responses.

- Try a different OS or (better) different PC, a normal live CD will do.

- Add "nameserver 8.8.4.4" to /etc/resolv.conf (above all other nameservers, and tit's the one from google, always working)

- Get newer/better drivers. Or older.

So I feel stupid but it apparently was my router, or something with the internet settings, however it was only affecting my computer for some reason. No one else had any problems with it. My stepdad was trying to set up new security cameras and screwed up the router settings in the process, so he just started over and set up the router from scratch and now I have no problems.

Thanks for the help however, learning new troubleshooting tools is always helpful.
