Ubuntu :: PPTP VPN Connection - Internet Really Slow

Jan 29, 2011

I recently installed Kubuntu 10.10 on my machine, and I configured the PPTP VPN connection through which I connect to the internet. I can successfully connect, but it works really slowly. Slower than it does on Windows 7 on the same computer, with the same settings for the PPTP dialer. In about 20 minutes after I connect, the connection fails and even the modem restarts itself. I tried setting the MTU for the pptp connection to 1400 (I checked, and 1372 is the maximum value before the packets start to fragment + 28 bytes for the IP/ICMP headers), but nothing seems to help.

Server :: No Internet Traffic Through The PPTP VPN Connection?

Feb 21, 2011

everything works fine, clients can connect to the vpn server with no problems and they can ping local machines! but no internet access through the vpn connection unless i uncheck the default gateway option on my client machine which is not what i want. I want my clients to get my server's ip address. my server is behind a router (router's ip : 192.168.0.1 | server's local ip: 192.168.0.100) so i used localip 192.168.0.100 & remoteip 192.168.0.234-238 in pptpd.conf. it think there is something wrong with routing or firewall rules, because it seems that the DNS resolution works .. when i try to browse a website my browser says "Waiting for xxxxx.com..." and it stays on that stage forever ! the funny part is that google.com works fine (don't know how).

p.s :
* I have already opened the port in on my router. I even tried it locally to make sure that the router is not the problem here. * already added ms-dns 208.67.222.222 / ms-dns 208.67.220.220 to pptpd-options. (found another guide that suggested to do this, before adding these two lines even dns resolution was not working.)

Ubuntu :: Slow Internet Connection In 10.04?

Sep 30, 2010

I have dual boot OS and I'm using Ubuntu with Win 7. Previously I was using Fedora but I thought to change the flavor! So I installed Ubuntu, but now I'm truly facing problem with my Internet connection! Its too slow in Ubuntu, the both surfing and downloading speed! Usually in windows I get 200-400 kbps download speed when downloading a file and if I download the same file in Ubuntu using flashget I'm getting only 60-70 kbps speed! Also the surfing is too slow! My broadband's bandwidth is 2.1 Mbps!

Ubuntu :: Internet Connection Very Slow On 9.10 But Fast In XP

Mar 23, 2010

Like the title, that is my problem. I'm using cable modem with 3mbps. It is Linksys Docsis, wired networking. When I download a file using ubuntu 9.10, my latency time (ping time) sky rocketed to 2000ms average, while in XP none of this happens; I tried to download the same file from the same website. In ubuntu 9.10 my network setup will be, well... nothing. I'm using DHCP automatic detection. Same thing in XP.

I don't want to go back and forward using XP for the internet. Funny thing though, none of this happens while I first started ubuntu 9.10. I didn't configure anything with networking. It is the way it is from the beginning. The only thing I tried was ubuntuone. But that like months ago, and the problem I have with slow internet connection only appear this March.

Ubuntu :: After Upgrading - 10.04 - Internet Connection Is Very Slow

Jul 5, 2010

After upgrading, my internet connection is very, very slow. Some sites pop up like always, but most take a very long time to load. Some as much as 3 to 5 minutes for a site that should just "pop" up.

It is not the internet connection, if I boot into windoze it is as fast as ever and I have a quite fast connection. It has just started this with the upgrade.

Ubuntu :: Internet Connection Is Sometimes Blocked Or Very Slow

Dec 12, 2010

I am using Ubuntu 10,04 with a gnome interface on an ASUS K70IJ. It all works well, just the internet connection is sometimes blocked or very slow. I have tried it on several places (offices, hot spot, friends) with wireless lan and ethernet. I thought it might be a problem with the pilot for the internet connection. Can anybody tell me where I could find such a pilot and how I do to install it?

Networking :: Internet Connection Really Slow In LAN

Dec 15, 2008

I use Slackware 12.1 and I have a big problem that I can't solve by myself. I'm connecting to a LAN where there are almost 20 PC connected, all with static IP.

my ip: 192.168.1.205
netmask: 255.255.255.0
gateway: 192.168.1.1
DNS server: 80.58.61.250, 80.58.61.254

I configured manually it but it doesn't works well. I set up the DHCP server on Windows 2003 so I tried to configure it with dhcp too. It gives addresses from 192.168.1.200 to 192.168.1.240 there are no PCs connected with DHCP at the moment, so my IP is only mine.

My problem is the following:

It takes a lot of time connecting to a internet web site! It's really strange because downloading a file the transferring rate is good, it takes some time starting, but it works normally. I wait almost 7 seconds after seeing a web site. All the others PC's (windows xp) can connect perfectly to network using static and DHCP. Trying with another wire in another room I've got the same result. My /etc/resolve.conf is configured with the IPs specified upper in this page.

Networking :: Slow Internet Connection

Jan 17, 2010

I set up my linux router as a simple NAT router. I use CentOS 5.4. When I set up ISP proxy IP in the browser of client PC, Internet access is fast. When I remove ISP proxy IP from the browser, Internet access is slow.

ISP use transparent caching but I can use manual caching as well. Clients on my network with transparent caching get slow internet access and using ISP proxy get fast internet access.

ISP announce that we can use transparent caching or manual caching.

So, I set up my linux router with squid. I set up cache_peer TAG point to ISP's proxy IP. But the problem is the same. Using my squid proxy is slow and using ISP proxy directly is fast. All other network settings are correct.

How can I improve my internet connection using transparent caching. I don't want to set up proxy IP address on all clients.

May 12, 2011

I've installed recently Ubuntu 11.04 and the first problem that I had was with my wireless lan card Wl-138g V2. The card was not enabled by the system, however after following one of Ubuntu's forum thread I managed to solve it, but... and there is always a but the internet speed is very low.When I had windows installed I faced the same problem and it was solved with an update in the driver, does any one experienced the same in Ubunutu?

I want to install KDE from fedora 14 DVD as my internet connection is very slow. It was a failure when I tried pointing the yum.repos.d/fedora.repo file to DVD to install using yum. Should I create a repository like what we do in RHEL to configure yum server(How to do it in fedora ???) Or is there any other method to install KDE repository on my system.

OpenSUSE Network :: Internet Connection Slow In Certain Applications?

May 17, 2011

I have recently moved countries and have finally got my internet connected today after a lengthy wait. I have a pretty fast connection - it's a fibre connection at approx 100Mbps Between my onu (modem) & computer (Lenovo SL510) I have a cisco wrt120N wireless router. I'm using Opensuse 11.3 (also dual boot with Win7)

My problem is . . . When I enter url in firefox (4) I get the message "looking up www. . ." for approx 5 to 15 seconds before anything starts to load. I also have the same behaviour in konqueror, firefox and yast software manager.

If I use Google Chrome the pages load instantly. Even never before visited pages.

A typical webpage such as Stuff.co.nz - Latest New Zealand News & World News, Sports News & NZ Weather Forecasts takes approx 20 to thirty secs to load in firefox and 3 seconds in Chrome. I can see the same behaviour always whether Chrome used first or firefox used first - so cache does not appear to be the issue.

If I boot into Win7 - websites load instantly there also.

I have updated to the latest wireless drivers for my system - but the behaviour is also evident if I attach a lan cable.

Here is a little info

Code:
/sbin/ifconfig
eth0 Link encap:Ethernet HWaddr 60:EB:69:AE:C6:28
UP BROADCAST MULTICAST MTU:1500 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0

Networking :: Internet Connection Fine In Windows Extremely Slow In Fedora 14

Dec 10, 2010

I've been troubleshooting this problem for several hours now and I'm out of ideas. My internet connection is fine in Windows 7 but an older computer I resurrected (AMD Athlon 1.7 GHz, 512 MB RAM, Fedora 14 Security Lab Spin) is having the stop-and-go's with its internet connection. It will work for very briefly, then it gets extremely slow, where any page I try to navigate to in Firefox 3.6 takes forever to load.I have a DSL connection and my DSL modem is connected to a Linksys WRT54G2 router. I set up a static IP in Windows but don't know how to do this yet in Fedora 14, and I need to get my internet connection working so I can troubleshoot further, but with it being so slow, I'm having to use Windows to search for problems and then switch over to the Fedora box via KVM (IOGEAR), which I also just started using. I don't think that would be related, but who knows.

Fedora Networking :: Internet Very Slow / DHCP Doesn't Work W/ Wireless Connection

Jul 17, 2009

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?

OpenSUSE Network :: Adsl Modem Acting As A Bridge To My Router Setup - Connection - Internet Went Slow ?

Jun 19, 2011

I have an adsl modem acting as a bridge to my router my setup was working well for more than year now , but then the internet went slow . I set the modem back to PPPoE the problem was with the DNS server of the ISP so using ifup i set the dns t 8.8.8.8 (google) the connection is back , but when i set the modem back as a bridge slow internet does the router know that my dns is 8.8.8.8 or i should set the dns on the router ? I can't see an option to set the dns on the router ( i just enter my username and password from the isp to use PPPoE mode ) by the way i called the isp support they kept telling me to restart , i told them i did but i never restarted my pc . I'm sure if i tell them i'm running linux they will blame the os !

General :: Bodhi - Internet Connection Slow/times Out: Ath9k/Atheros/TP-Link USB Wireless Dongle

Jul 31, 2011

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.

Ubuntu Networking :: PPTP Connection Failing With LCP Timeout

I'm using Kubuntu 9.10, my pppd version is 2.4.5 and pptp is 1.7.2 I'm trying to connect to the iPredator VPN service, but I keep running into problems with LCP.

[Code].....

(I've got "defaultroute" in my /etc/ppp/peers/ipred config file.) Any ideas what could be causing this? Could it even be my router? It claims to support PPTP, but considering it claims a lot of other things which aren't true, I wouldn't be surprised if it was the culprit.

Ubuntu Networking :: PPTP VPN Connection Stopped Working?

Oct 6, 2010

I managed to set up a PPTP VPN connection in Ubuntu 10.04, and it worked first time.This was about 3 months ago. It was working yesterday (Oct 05 2010), but when I came to log in to the VPN today it doesn't work. I tried the same VPN connection on my wife's laptop which runs Vista and it works. I have tried re-entering the details, even deleting and setting up from scratch via network manager. And yes I have the correct VPN plugins. what I should do. Is there a log file so I can have a look at it to see what the problem is. If there is where is it located. The computer is able to connect to the internet without any problems, just can't connect to the VPN. The only thing I can think of is that the update manager popped up this morning so a few things have got updated today. maybe something in there broke the VPN connection.
