Ubuntu Networking :: Wireless Internet Freezing Leading To Slow Computer
Aug 3, 2011
I first noticed the problem because my wireless internet will stop working. The usb stick has its LED constantly on but it fails to connect. I have tried some methods of restarting the networking, like "sudo restart network-manager", disabling and re-enabling the wireless and networking from the taskbar applet. I tried removing the module and restarting it. It might be a bigger problem because I'll find that things will randomly hand for awhile, like opening system monitor, or running terminal commands. They do eventually run but only after several minutes. A restart seems to get everything working again, but the problem comes back at random times. I am willing to solve this right now as I have time, just let me know what info you need and I will post it.
Update: Some more info I forgot to include. I am running Ubuntu 11.04. It just froze again, I tried logging in and out but the internet still wouldn't work and things were hanging, I couldn't get file manager open. I have even tried shutting down the computer and had it stall on the Ubuntu logo with the dots loading so I had to hard restart.....

I have configured a squid proxy server with @2 eth in different network subnet and with site blocking and extn file download blocking. One eth0 for office wired network and another eth1 is for office wireless network for laptop use for guest and visitors.
The problem is [URL] is an Indian government website, which is not working though this proxy server and the Internet Explorer is getting very slow and freezing the computer. In alternate I have configured a another test server with squid proxy with out any security and test the same. the problem is still with the all the computer in the network. The above website is perfectly working with Gateway configuration in TCP/IP properties in Network Configuration in MS Windows XP computers but through squid proxy its not working.

The first two times I entered the wireless key on the prompt that appeared shortly after login, the computer froze completely. ctr-alt-f1 ctr-alt-backspace did nothing. The third time, I closed the first prompt and after 10 minutes I tried connecting again. It didn't freeze, at first. The internet worked. It took about 10 minutes later for it to freeze. Now, whenever I boot up, it freezes a few seconds after login. I can boot recovery mode, but I don't know what to do from there. Heres some info I got from the recovery mode:
Computer Brand: Sony PCV RX850
Ubuntu 10.4 32 bit 2.6.32-21-generic i686
Realtec 8185L chipset

I have 2 computers connected to my linksys router via ethernet cables.
My main computer is running Ubuntu while the other is Xubuntu.
When both comps are on, the internet works fine, but when my second computer is off, my main computer has super slow internet. Sometimes it takes 2 minutes and I get "This webpage is not available", and then I refresh that and it finally loads.
Why does it work when both comps are on? What could cause this?

I installed 11.04 last week. Everything was working brilliantly until I turned on my laptop today. Now my wireless internet is running soooo slow. Requests take like 5 seconds, then it loads the page for about 10 seconds. Last night it was running fast.Chrome/Chromium/Firefox all run super slow. I tried turning off wireless-N and using G instead, but that didn't help. My windows 7 desktop is not experiencing the same problems in Chrome, or Firefox. I'm not sure if it's updates that I installed yesterday that didn't take until I restarted today

I am currently using opensuse to run a server, however I am experiencing some difficulties. Every once in a while, and I mean completely randomly. This will occur out of no where, and then not happen for five days, then occur twenty times in a row. What happens is the computer runs fine, and all is well but suddenly it wont connect to the internet. All applications are fine and everything is working. It isn't frozen, just won't load webpages. I am using a belkin 111v2 wireless g adapter and it usually works fine.
So when the internet freezes, if I unplug any usb the computer freezes. The mouse stops moving and the keyboard won't respond. The caps lock light won't even turn on. However the laser on the mouse is on, but the computer won't respond. Its like its shutting off the usb hubs. The only thing to do is force shut it off and restart until i no longer have the problem. Sometimes it helps if I open it and re-seat the ram, but that gets old. Does anyone have a solution?

Let me start by saying that with the previous kernel 2.6.31.5 when I opened network configuration, it didnt even recognize my card when i'd go to modules. After I updated to 2.6.31.8 it didnt recognize it until I installed the ralink-firmware 1.1.3.5. After that I could configure it using rt2870sta setting in modules. But once I restarted it would freeze after a few seconds after I could see the desktop on startup. I reconfigured the card to be 'manually' powered, but now it just freezes when I click on the access point I want to connect to. When it freezes the caps lock and scroll lock start blinking and the only way to turn off is holding the power

I am a convert from Ubuntu (9.04 kept freezing on my laptop; when it did work, many packages it seemed were outdated--ie only Eclipse 3.2, rdesktop was messed up [and apparently is also in Fedora]), and I am having some trouble with getting my wireless working.I am running Fedora 11.First off, there is a problem when trying to connect when using DHCP. NetworkManager gets to the second green dot, and then after a short while I am given a message that the connection was disconnected.
Configuring the interface manually, not using DHCP, allows the connection to complete. However, the internet is very slow. There is a 15-30 sec delay before website loading actually commences, and then another delay each time an ad must be fetched from another server.How can I fix this delay? I know I have encountered it in earlier versions of Ubuntu, but I can't remember how I fixed it.About the rdesktop problem, if anyone is able to help [maybe I should post another thread?], the cursor color (the color of the pointer) is inverted---where it should be white it is black, and where it should be black it is white. I use rdesktop a lot to connect to my terminal server in my basement. Any idea how to fix it?

I am wanting a computer with an external dialup modem (ppp0 modem through a com port /dev/ttys1) to act as a gateway to the internet, forwarding internet traffic through ethernet (eth0 is set to static 192.168.2.2) to a router (the router is 192.168.2.1) where it will be broadcast to other wireless computers like my laptop (192.168.2.3). I've had this setup until recently when the gateway computer (the one with the modem) died. Now I'm replacing that machine with another box and an install of Ubuntu 10.10 but so far things aren't working for me.
Success so far:I have dialup access working on the new box. Took me a while to work out the configuration for getting dialup working, though the IP address is Dynamic (or it won't stay connected), "Check carrier line" is off, and "Ignore Terminal Strings (stupid mode)" is on in order to successfully connect and stay connected to my ISP. I also had to make my normal (non-root) user "lancer" a member of the "pid" group (the reboot) in order to use gnome-ppp as non-root. The laptop (192.168.2.3) is successfully connecting to the router (192.168.2.1) as I can see the router configuration page when I type http://192.168.2.1 into the laptop's web browser. This setup is unchanged from how I had it before when this was previously working and I don't want to change how the router itself is set up. What I want is to know what to fix in the new box in order to get it connected to the router (through ethernet) and bridging the internet through.
My problem is that whenever I plug in the eth0 from the gateway (192.168.2.2) to the router (192.168.2.1), Ubuntu's automatic plug-me-in network detection kicks in and I find my dialup no longer working through some kind of IP conflict (at least that's what I think it is). Maybe I don't have the "gateway" correctly assigned? (in the gateway computer for the ethernet connection, I had it pointing to itself as I don't know what to put for "gateway IP" as that is automatic So, just to check my connection, here I am pinging google (from the gateway computer which has the dialup modem) once a dialup connection has been made.
Code:
lancer@lancer-desktop:~$ ping www.google.com
PING www.l.google.com (74.125.237.17) 56(84) bytes of data.
64 bytes from 74.125.237.17: icmp_req=1 ttl=55 time=179 ms
64 bytes from 74.125.237.17: icmp_req=2 ttl=55 time=176 ms
64 bytes from 74.125.237.17: icmp_req=3 ttl=55 time=158 ms
[Code]...
What do I need to do in order to make Ubuntu of my gateway computer stay connected to my dialup but also simultaneously share an ethernet LAN to my wireless router and feed traffic to the other computers from there? I have googled this but some of the most promising instruction (e.g. http://www.ubuntugeek.com/sharing-in...in-ubuntu.html) call for packages like dnsmasq or ipmasq which seem defunct now in Ubuntu 10.10. Other pages seem to suggest dual-networks "can't be done" in Ubuntu [URL].. (what!?! I had it before my other gateway died)

I have cricket wireless broadband and the starcom um100 usb stick. It reconized it when I first put it in and was able to set it up. I connect to the internet and I am able to go to one or two pages before it freezes on me.
I ran the lshw -C network code and this is what I got it doesnt see my wireless
When I connect my wireless it does see it when I ran the lsusb code ( it didn't see it before when I didn't have it connected)
Here are some screen shots of what I got when I ran these codes:

I was running Ubuntu 10.10 and my wireless Internet was very slow (~1 minute to load a website, and downloading was excruciating). I dual boot my machine with windows 7, and I have no wireless problems at all when I am running windows. I disabled IPV6 and that did not do anything.I recently upgraded to Ubuntu 11.04 hoping that this may fix the problem however my wireless internet is still very slow. When I plug my computer directly to my modem, I have no problems at all.I was wondering if anyone had any ideas as to what might be making my wireless Internet so slow when I run Ubuntu?

When I had OpenSuSE 11.3 installed originally, I never had any slow internet connection until I erased the hard drive and went to 11.4. This is what my configuration looks like on /usr/sbin/iwconfig:
Cell 01 - Address: AA:AA:BA:BA:AB:BB
Channel:11
Frequency:2.462 GHz (Channel 11)
Quality=70/70 Signal level=-37 dBm
Encryption key: on
ESSID:"housewifiZZZZ" .....
The device I am using is a D-Link DWA-160 which is running the ar9170usb driver (and did on the previous version)
These are the steps I did:
Disable IPv6 from the global tab on Network Settings.
Set DHCP version 4 only in dynamic address in address tab.
Used the anti-IPv6 switches in firefox making these changes
Network.dns.disableIPv6 change from false to true
Network.http.pipelining change from false to true
Network.http.pipelining.maxrequests change from 4 to 8
Added ipv6.disable=1 in DEFAULT_APPEND in Bootloader
(I couldn't find bootloader _APPENDS that was stated in another forum)
Switched from ifup to NetworkManager for Network Setup Method. Reinstalled OpenSuSE 11.4 with Ubuntu 11.04 (to see if it was OS issue) and it still didn't work, so I switched back to OpenSuSE 11.4. Is there anything I did wrong or do I need to do anything additional?

This problem started a few days ago. Whenever I attempt to connect to a wireless connection via network manager, my computer completely crashes, going to a black screen with no input from keyboard or mouse. It forces me to reboot using the power switch. Everything works fine when I connect to an ethernet cable, so I am sure it's a problem with my wireless driver.
I already tried (successfully) reinstalling the ath9k driver via compat wireless as was the advice from other forums, but this had no effect. I'm currently running opensuse 11.4, and haven't had this problem until a few days ago
This problem seems a bit ridiculous for a task as simple as connecting to a wireless network, so I'm convinced that either there is some sort of relatively simple way of fixing it, or windows really is the only decent operating system out there..

Just re-installed Bodhi. Ran update, dist-update, set up connection and connection still slow or timing out and reporting errors in 'iwconfig'. This is 3rd re-install of this version. Have also tried 3.0 kernel and pae versions of Bodhi. Cannot get this connection up to speed and without errors. Atheros chipset ar9271.
Sorry for weird subject line and opening paragraph. Trying to make it easy to find and browse in case this gets solved and can help someone else. Not being a Linux guru, I can only hope to help others through my mistakes and ignorance.
I followed instructions to update driver listed at Linux Wireless.
In addition to following the directions at Linux Wireless, I also downloaded the GUI Program to install ath9k_htc.
No luck. My connection reports 1M/s and is reporting "invalid misc:" errors in iwconfig.
I'm running Midori browser but apt-get and wget are also downloading slowly.
I'm connecting to a Zyxel 660 series router using WPA/WPA2.

I used to have Windows XP on my desktop computer which was changed to Linux 9.10 awhile back and just recently I downloaded Linux 10.04. I am having problems with my screen while viewing websites and games I play freezing up. I have also noticed that it is very slow at times downloading sites I wish to view. The sound on videos and games comes and goes. I thought by upgrading to Linux 10.04 would fix the problems, but it has not.

I recently installed Ubunto 10.10 (the netbook version) onto my Acer Aspire One Netbook. The OS it came with was a very old Red Hat, so I got rid of it. I am a complete Linux newbie, and not having the best experiences so far. Basically, the netbook is completely clean with Ubuntu just installed. It's not got any files on it or any extra software. But it runs REALLY slow.
Boots up pretty quickly, but it takes ages to do anything. It'll either just run ridiculously slowly, or it will run okay for 10 seconds and then not do ANYTHING for the next 10. I have never been able to play an MP3 track without the whole thing freezing, let alone a video.Why is it so bad? The machine's not that old (maybe a year and a half) and the OS is brand new. There's no files or added software on it. What's the problem? Is there anything I can do? It's so frustrating! And it's the the only computer I've got at the moment.

When using launchpad and the ubuntu daily build website it is very slow. I get 1.2mb/s normally and the speed drops quickly to 0kb/s This is the case from any version of ubuntu that is installed on my laptop.In windows it is no problem, equally there is no problem from a live cd or an install on my external hard disk. Is canonical blacklisting/slow listing my ip?
I am behind a university network but am sure this problem occurs at home .I did a clean install and had no problem until about an hour ago. When I tried to re download a project using bzr my speed instantly ropped.I had downloaded it fine a couple of hours ago. I hope that someone can shine some light on this, its very hard to work on projects if I can't download them.

I'm staying out at a friend's house in the middle of nowhere, and she's been complaining about how slow her satellite internet has been of late. So I decided I'd take a look. If I ping my server at home, I end up with these statistics:
Code:
// @ 1 ping probe per second
60 packets transmitted, 36 received, 40% packet loss, time 59172ms
rtt min/avg/max/mdev = 639.915/799.882/1209.119/104.763 ms, pipe 2
Compare that to driving 70 down the highway tethered to my cell phone: I see latencies in the 3000's and out-of-order packets, but practically none get dropped. If you ramp it up to 5 ping probes a second, the loss climbs to around 75%. To me, that seems quite excessive. The interesting thing is that all the packet loss seems to be occurring on download traffic - I set up tcpdump to monitor the packets on my server during the ping test, and all but 1 of the pings to got there, so the other 25 lost packets wondered astray on the return trip. I tested it with the client directly connected to the modem (it had the public IP).
So I'm quite certain that it's the satellite link itself that is the issue here. I've attached the complete logs from the ping test for your enjoyment. Of course, TCP corrects for the loss of packets, but with a latency of 800ms, resending packets takes a significant amount of time, not to mention services like DNS that just wait for a timeout to elapse (which is usually way too long). It can take 15 seconds to load a webpage. So I guess my question is, should it be this bad? I know satellite is generally terrible, but I didn't expect to see such rampant packet droppage.

I just installed dual boot Ubuntu 10.04 on my WinXP laptop. The laptop is a Compaq v2552us.
In windows mode, the internet works plenty fast.
In Ubuntu, I can't download a single update for hardware drivers or for ubuntu (it says there are 74 though).
It starts to DL, but max speed is about 800B/s, but that only last for a couple seconds before it switches to unknown. I am connected to my wireless router via cable, can't even get wireless to work (I suspect the aforementioned hardware drivers, which is why I need this to work).

I am trying to connect my desktop to my laptop over a non-internet connected LAN, but when i enable the LAN connection on my desktop (the one with the wireless) its internet stops working.
it is a very similar problem to this except that i am using ubuntu for the machine with the two connections.
right now i have my wireless on the 192.168.1.* address space, while the LAN is to be on 192.168.5.*
note: my goal is not to share internet with my laptop, just be able to connect to it and the internet at the same time.
desktop: ubuntu 9.10 , wireless and LAN
laptop: windows xp, LAN only
