Networking :: PPPoE Slows Or Does Not Load Certain Websites?

May 9, 2011

I'm having a weird problem that I'm hoping someone can help me with.

First some specs:
F13
NetworkManager Applet 0.8.3.998
Driver r8169
Opera 11 and Firefox 3.6.16

Recently my ISP switched to PPPoEand since then my internet connection has been giving me problems. While browsing, some websites load fine, some websites load fine after I refresh once or twice, some load really slowly and the formatting tends to be messed up and some websites won't load at all (they stop at waiting for website...). Ping for all of these sites is however fine. Also uploading and downloading either from sites like rapidshare or using torrents is also fine. The same ISP also provides a second similar connection which is connected through a wireless router (mine is connected directly - no modem or router) to two computers (one via a wired connection and one through wireless) both running Win 7 and everything works fine over there.

Things I've tried. I tried using the router changing it's setting to my connection and connecting through that but the problem remains. After googling I thought it might be an MTU issue so tried this:

This works for various websites whether they load or not. My MTU is set at 1492 but I've tried various lower numbers all the way down to 1300 but no luck. I tried disabling ipv6 in Firefox but no change.

Networking :: Websites Won't Load - Using OpenSUSE 11.2

Mar 9, 2010

I'm a first time poster and new to openSUSE. I've had a small amount of linux experience and even studied UNIX a few years ago - unfortunately, to paraphrase Homer Simpson, "as something new enters my brain something old has to leave". In this case nearly everything I learned about UNIX

Anyhow, ms problem is this. I've installed 11.2 with KDE desktop. Using either Firefox or Konqueror browsers, I am finding it impossible to display any webpages, other than Google. All google websites, such as gmail, calendar and searches work perfectly. Unfortunately, I can't directly enter a url into the address bar nor can I link from a google search.

I've hunted high and low for a solution but have failed to find one.

Ubuntu Networking :: Cannot Load Most Of The Websites In GUI (they Get Pinged)

Jun 17, 2010

I don't think I changed anything in my system's configuration, but I wasn't able to access most of the websites. Some loaded perfectly, but for a vast majority of them, Firefox (And every other GUI browser - I tested Opera and Chromium) just showed me a never-ending loading screen. At first I thought it was my ISP, but on the same computer when I booted up Windows XP, everything worked fine.

I then booted Ubuntu back and tried pinging the nonaccesible domains - and they all work! Even weirded - for some of the domains the page's title gets loaded, and nothing more - even in something like 30 mins time. For some, I just get "Loading..." message. And some, as said earlier, work just fine. But I can ping all of them. I wanted to ask You about that issue, but ubuntuforums.org didn't even load. I then tried to use CLI browser links and it works just fine for all my sites and here I am, writing this topic from CLI mode in Terminal.

Ubuntu Networking :: Can't Load Websites When Torrents Are Downloading

Nov 28, 2010

This is sorta a strange problem as it also happened in Windows Vista as well, one of the reasons I tried out Linux was to fix this problem (then fell in love with it and didn't go back).

Anyway, problem is that when ever I start downloading a torrent, no matter what speed the file is downloading at - fast or slow, as soon as I open a browser and then load a website it's like my internet connection has died. "Chrome was unable to find the website" "Firefox could not load this site" ect ect.

The torrents will still keep downloading/uploading, instant messages programs still work, but websites will not load.

Ubuntu Networking :: PPTP Server Some Websites Don't Load?

Jun 24, 2011

Running Ubuntu 11.04 Server 32bit fresh install

I did this walk-through trying both iptables and ufw

I am able to connect to my VPN server using both windows 7 and Ubuntu desktop just fine, and using wireshark verify that all packets are being compressed and sent through the VPN tunnel.

Many sites work but there are several that will not load while using the VPN, one of them is ubuntu forums also sourceforge.

I can ping the servers while connected but the websites just will not load, and time out. The second I disconnect from the VPN they load instantly.

Ubuntu Networking :: Websites Taking Ages To Load / Sort It?

Basically i just downloaded and installed Ubuntu 11.04 and i love it, however all websites wont load except for ubuntuforums.org and google.com which both seem to load instantly. Any ideas?

BTW i am connected to the internet obviously and i am also writing this on ubuntu. I don't understand why this is happening because all websites seem to load on windows and the package installer seems to work fine.

Fedora Networking :: Websites Won't Load After Running A "yum Update" In F13

Apr 10, 2011

I'm having a problem loading websites after a yesterday's "yum update" on F13. Before that everything worked fine but now when I open a browser, websites only load for about 2 seconds, after which any website I open just goes into a constant loading loop. I tried disabling the IPv6, as some threads suggested but it didn't help and pages still won't load. It happens on Opera and Firefox, so the problem seems not to be browser related. The connection is fine too, as I it works ok under Windows.

Fedora :: 10 Internet - Websites Load Fails And Shows "Page Load Error"

Dec 10, 2009

I reinstalled fedora the other day, and it's been working just fine, apart from the internet. It shows that I have a full connection with the wireless network, but it's really difficult to actually load a page. 80% of the time it just fails and shows "Page Load Error". It's really frustrating because it is connected to the internet. In fact, the icon in the address bar even loads from the site I try to access, but websites just will not load.

I've tested my wireless internet with another laptop which is running vista, and it works perfectly on that. Also, I'm running Fedora 10 on an Acer Extensa laptop.

OpenSUSE Network :: Connecting To Home Wireless In 11.3 - No Connection (websites Will Not Load)

Jan 22, 2011

I've just installed openSUSE 11.3 for the first time on a Dell E1505 notebook and am having problems connecting to my home wireless network. Using the Network Manager I've been able to find my home network and connect after entering the network password. After a minute or two the wireless network is still shown as active but their is no connection (websites will not load).

I'm completely new to Linux so I have almost no clue what could be causing this. I have tried connecting the notebook hardwired (Ethernet) to the router and get a perfect connection if that information helps any.

Networking :: Windows PC Slows Down My Network ?

Dec 12, 2010

I have a Actiontec m1000 modem from Qwest that seems to offer more speed to my brothers Windows PC then my Linux PC (same make and module) I checked the ping on all systems, and they all look fine. The only thing that seems different is the number of open sessions in the modem, Linux only uses 2, and Windows uses 80. My guess is that the modem uses sessions to control the bandwidth, but I don't know how to add sessions to Linux networking to compete for bandwidth. I did test in the same browser.

Ubuntu Networking :: Wireless Slows Down When On Battery ?

May 31, 2011

I have Ubuntu 10.10 running on a Dell Latitude E6500 notebook and am using the Broadcom STA wireless driver (just in passing, same happens on Mint 10).

My problem is this:
- when the computer is plugged into a power outlet, wireless works fine, but
- when the computer is running on battery, it hardly works at all: The network strength indicator item still shows the same connection strength but data are not transmitted anymore or only extremely slowly (google.com might 2 minutes to load).

The drop in performance literally happens 1 sec after unplugging it, and once the notebook is plugged into external power again, it resumes after a few seconds. (I have tested this with big downloads where you can see Firefox's or the Update Manager's download speeds.) The BIOS doesn't seem to have power saving settings that make that happen, and I haven't found any in Ubuntu.

I am programmatically doing a large FTP upload (about 5 Gb's of 2-3 Mb files) from my Windows 7 machine to a ProFTPd server on my Ubuntu box. When the program is run, transfer rates are huge! but as run time continues, transfer rates drop off significantly and eventually slow to a halt resulting in a:

The rest of the uploads fail due to Socket Read Errors.

Why is the transfer failing like this?

Ubuntu Networking :: PPPOE Cant Run?

Jul 16, 2011

I use win7 bit and input the ISP username and password, it runs well,but after I swap system to Ubuntu 11.04 64bit, I cant use the username and password to run DSL successfully.I use the

PHP Code:
sudo pppoeconf 

A text-based menu program will guide you through the next steps, which are:

Confirm that your Ethernet card is detected.
Enter your username (provided by your ISP).
Enter your password (provided by your ISP).

If you already have a PPPoE Connection configured, you will be asked if it may be modified.Popular options: you are asked if you want the 'noauth' and 'defaultroute' options and to remove 'nodetach' - choose "Yes".[code]................

Networking :: Pppoe Firewall Security ?

I got a new ISP, and it uses PPPoE. Let's say it's over eth1. After I connect there is a ppp0 -or similar interface. My question is what kind of firewall policy should I use on eth1? (block all, allow ppoe passthrough only or should I just do nothing?)

Networking :: PPPOE Over Wirelesss Modem

Apr 24, 2010

I'm using Ubuntu 9.04 ..

My adsl modem is in bridge mode . I can connect to internet via pppoe . pppoeconf recognise the pppoe in eth0 and setup a connection and i can use it .. Now , the Problem :

How can I setup a pppoe connection using pppoeconf so that it uses wireless ? I set the wireless mode to bridge in modem settings . But , after that , the access point stopped appearing in "aps in range" in network manager and i can't connect to it . pppoeconf also doesn't recognise wlan0 as a valid pppoe link . but dat is normal since i don't think it can check if wlan0 is pppoe without wlan0 being connected to the modem's wireless network .

SO , HOW CAN I CONNECT TO INTERNET WITH MODEM IN BRIDGE MODE AND CONNECTING VIA THE WIRELESS INTERFACE OF THE MODEM ??

sidenote : hey , is pppoe over wireless even possible ? coz the datalink layer of wlan is not ethernet rite ?

Networking :: Odd PPPoE Packet Redirection Networking?

Feb 7, 2010

I have a machine with two network cards running linux mint 8 XFCE (which is compatable with Ubuntu Intrepid Ibex). eth0 gos out onto the network propper, has a static IP address of 10.10.10.10 and serves DHCP requests for the 10.10.10.x subnet.

eth1 is pluged into a PPPoE concentrator, and has a static address of 192.168.0.1 (I would have left it alone but pppoeconf wouldn't work unless it had an address).

ppp0 is the piont to piont over ethernet conection that is corectly created when I run pon. I have both guard dog and guide dog installed but they are both disabled.

Now, the weird part: I can ping the IP number of the machine at the other end of the pppoe conection (when it changes I can still ping the new number), the local IPs (10.10.10.x), but *nothing* else not even the DNS servers passed to the machine during ppp conection which are in the same sub net as the machine I can ping.

When I try to ping or trace the route I get an error message like: reply from 10.10.10.10: desination unreachable There is nothing wrong with the network at the other end, as I can make an Identical PPPoE connection from other machines on the network if the the concentrator is pluged into the hub (a rather unsafe place for it to be) and it all just falls into place.

What seems to be happening is that the machine is treating eth0 rather than ppp0 as the internet gateway, and passing the packets round in circles.

Fedora Networking :: F11 - Routing Two PPPOE Connections

May 24, 2009

On a Fedora 11 machine, I configured ppp0 on eth0 and ppp1 on eth1, each one is connected to a modem, I also defined ppp0 as the default gateway.. Should I do anything else to load balance the 2 connections or will ppp1 take some of the load by default? Should I add any other routing rules? If yes then please tell me what should I add, keeping in mind that for each pppoe connection both the pppoe address and the remote address are not static so I actually needed some scripting to change the default gateway each time the remote pppoe address changes.

Fedora Networking :: PPPoE Not Working After Update?

Feb 26, 2010

I'm running Fedora 12. After installing the following updates (from yum log):

Quote:

Feb 24 14:34:25 Updated: xorg-x11-server-common-1.7.5-1.fc12.i686
Feb 24 14:34:45 Updated: 1:qt-4.6.2-1.fc12.i686
Feb 24 14:34:50 Updated: compiz-0.8.2-24.fc12.i686
Feb 24 14:34:51 Updated: 1:qt-sqlite-4.6.2-1.fc12.i686
Feb 24 14:35:13 Updated: 1:qt-x11-4.6.2-1.fc12.i686

[Code]....

P.S.: I have another F12 system, on a second HDD, that I haven't updated since two weeks ago and I can connect to the internet with it. So this seems like a package correlation problem. I think it might affect more users than just me, especially those who only have F12 installed on their computers.

If this affects more than just me, I think the guise at Fedora should offer a script or a rpm to be used offline to, whether downgrade the "ppp" package, or to update the "/usr/lib/pppd/2.4.4/nm-pppd-plugin.so" plugin.
