A Student's apart and network problem ( Have to read , very weird one )

post #1 of 11
Thread Starter 
I stay in a student's apart and it has a modem and a router to give internet to nearly 30 people . The internet connection sometimes cant open websites, but sometimes it opens fast. I mean it loses pings and shows connection time outs. However recently I bought a VPN service to test. When I use vpn my connection never drops, or never time outs. BUt whenever I close the vpn same things that I mention above happens. So I decided to use VPN all tlme smile.gif Its really fast also. But I am wondering why vpn never loses connection , and real normal internet loses it? I am happy I find a solution , but look for an answer to this case smile.gif Any ideas ?

Not sure, a vpn should provide some extra performance loss. A vpn is just something that tunnels from your machine through your ISP to a remote server and forwards your request from there. So you still use your internet connection and router. If any of those are having issues, your vpn connection should have issues as well.

But I really see it with my own eyes. VPN is realy fast, but most importantly it never drops connecition. I think the router drops my connection or ip when there is overload on the network, but cant see me when I am on vpn and continues to serve me as usual. And never gives me trouble.I tried this more than 10 times to make sure and I am sure now. Thats I think that will be reason. Cause I tried to disconnect from vpn and use normal connection, I get so much connection timeouts, and reconnect it and from now on I dont get any dropouts. When I disconnect same things happen. So I get nearlly all my potential from vpn ( it gives me 8 mbit and my real connection is 8 mbit also ) I decide to never disconnect from vpn because the time I disconnect I get unstable connection and dropouts, high pings etc..

Do you have another computer to test this from, it doesnt sound like an external issue but more an internal one on your computer

Kersoz another possible reason you have such high timeouts and not able to connect to the internet is the amount of data speed provided by the student apartment complex. I experienced the same issue with the connection at the location I once lived at and they had a T1 line. But wasn't enough when you had over 800 college students connecting to it at one time. This may be the cause of the issue for you in itself. The next alternative is the complex has it set to where only a select few ipaddress are being used for the students in the complex itself. I believe its the data connection provided by the apartment complex inquire with them what internet speed they have. Ask what the exact Download speed and Upload Speed is.

That's a bit much for one consumer grade ap/router.

You could try to turn off deep packet inspection on the firewall, if that's even an option on your device.
This might explain why your normal packets get dropped while the router uses CPU to look through the contents while encrypted packets are more of a passthrough.

I'd also set up DHCP to give out 8.8.8.8 as a DNS address instead of the one from the router. That way the router won't have to use CPU cycles doing those DNS lookups.

I'm going with you on this one - that sounds very plausible indeed. But 30 people on a consumer grade router, like mentioned = probably not suited.

@OP

The fact that your VPN works fine, and that normal connections do not leads me to think that there's something interefering with the IP packets of normal web traffic. It looks like there's some kind of traffic management/Deep Packet Inspection happening somewhere on the campus network. I suspect that since your VPN software uses a different port to create the tunnel (e.g. 1194 for OpenVPN), it isn't being traffic managed, as opposed to ports 80 & 443 for HTTP traffic.
