PPTP Connection Problem

Hi,

I have to use PPTP VPN in order to connect to internet. I have a dual boot laptop, there is no problem with pptp connection in Windows 7 and my bandwidth reach to 8 mb/s, but in OpenSUSE 12.1, it wouldn’t go over 1 mb/s.
I have also created this vpn in both KVPNC and KDE-NETWORK-MANAGER, and the result is the same.
I want to blast Windows 7 out of my laptop but it’s not possible till this problem continues. Can anyone tell me exactly what is wrong here?

Thank you

You are not explaining very well.

PPTP (peer to peer tunnelling protocol) and VPN (virtual private network) refer to the same thing. You have not described what sort of connection you are (trying) to establish (e.g. IPsec, SSL, Cisco).

You would not normally use a PPT/VPN to access the Internet. Mostly the Internet is used to carry a PPT/VPN connectin two LANs.

Where did you get the terms “1 mb/s” and “8 mb/s” from? They are technically incorrect. Milli bits per second (mb/s) is not possible in the real world. 1MB/sec ~= 10Mb/sec. Are you measuring data throughput, or what?

Dear Eng-int,

Thank you for the reply.
I’m living in a student houses and I was given a user/password to create a PPTP VPN to connect to university’s network and internet.
And yes, you are right, I didn’t mean Milli bits, I should have written them in capital, so they are “1 MB/sec” and “8 MB/sec”.
I think information below might be useful to guess what is wrong:

You have not explained where you got those numbers from. You may be comparing apples with oranges.

Data throughput is generally measured in MiBps (Mebi bytes per second) and may take data cpmpression into account.
The link speed is generally measured in Mbps (Mega bits per second – related to baud rate).
However you cannot always believe what you read in output.

Are you connecting via wired ethernet or wireless?
Are you using one of Newcastle University’s docking points?

Did you use the ISS instructions here:
Connect to the campus network

Also if this is a wireless connection do you know what chipset and driver you are using:


# hwinfo --netcard
# iwfonfig
# iwconfig

give useful information

They have been measured with DownThemAll which is a download manager Add-on for Firefox and can be used in both Windows and Linux. I use it to download from Rapidshare with my premium account.
Yes exactly !! How did you find it ?! Are you here ?!

I used ISS instruction below to connect to the campus network:

Hey guys,

More than 10 days have passed from when I posted my problem and still I haven’t received any tips or solutions.
Can someone kindly help me with it?
