connection issues on laptop

i'm having some mega issues with my computer's network connection.

it is connected, i have an ip address, it browses, but the problem is it's SLOW as all hell! and it's not my internet speed-- even if i try connecting to my router's ip address, which would usually open the page in like 50ms, it takes like 30 seconds to resolve the ip, then either times out or loads super slow and skips certain images cause they timeout during load.


have checked for adware/spyware/viruses, all clear. i don't know if simply uninstalling and reinstalling TCP/IP would do the trick? any suggestions?
 
ok done some messign around....... not much better now, but the main issue is with https:// sites which basically just don't load. any ideas?
 
done. no luck 🙁

things effected: pretty much anything non-port-80, including torrents, aim/msn, any secure pages or gmail POP.

firewall is off.
 
When you say you checked for spyware, HOW thorough a check? Just running a spyware scan with Adaware is not enough. You could have BHOs, or a compromised HOSTS file, or any number of other issues. Refer to my detailed spyware removal instructions here: http://theflyingpenguin.com/spyware-removal.shtml

Are there any other computers on the network? If not, you can't be sure it's not a router problem. Could be as simple as a bad cable - packet loss from a bad cable will result in your exact symptoms.

If there are other computers on the network and they don't have this problem then the problem is not the modem or the router. Could be a bad port or cable that the misbehaving computer is on - try another port and cable. Could be the NIC on the computer is bad - try a spare NIC card.

If there are no other computers to compare to then your router is suspect. Have you tried resetting it (reset switch on the back) and re-flashing it? I've seen plenty of routers just go bad, or get their BIOS scrambled.

Have you tried connecting the computer directly to the modem?

Hope this helps...

problem is in firefox and IE too, and what further complicates the issue is that sometimes it connects, other times it won't- and when it does connect it's super slow.

i've also tried rebuilding the winsock stack, no luck. non-secure sites are running pretty much normally now, but once again, only port 80 stuff- soon as it comes to https, torrents, chat programs etc, no luck...

ran through the mega spyware removal thing you had highlighted. no luck.

also have tried directly connecting to internet (dorm connection), going wireless, and neither of those solve the issue...

this is quite annoying!

i'm on a dell inspiron 5100.
 
Has it got onboard virus scanner (MBR) - if so, can that be disabled - it wasnt what i was thinking about originally, but, what the hell.
Also, have you tried with a cardbus NIC to troubleshoot - and possibly isolate the problem.

no onboard virus scanner, don't think.

what software would you suggest to troubleshoot the NIC? although, i have tried it using wireless as well as wired, which are 2 different NICs. also connecting to other PC's on the network is flawless and fast as normal... you'd think that would be effected too, no?
 
network is fine
regular internet port 80 is fine for the most part
non port 80 and https is moody-- works <50% of the time, keeps giving timeout errors

no modem, direct connection to college network. have plugged another pc into the same cable (just tried it with a mac) and it works without a glitch...
 
yep, not a DNS issue.
wow, how annoying is this! i'm just gonna reformat later today, this problem is pretty annoying given how every important site is https!!
 
i thought you couldn't remove tcp/ip via that method?

i did use the tcp/ip restore utility by microsoft, and i would think that a windows reinstall (no reformat, just a repair) would do the trick... but no such luck. am reformatting now...
 
ok, reformatted ok. issue is surprisingly still lingering a bit... i feel it has to do somethign with one of the windows updates or something.

the problem only appears when i start any torrent program. from the looks of it it's not allowing me to open more than a certain number of TCP/UDP sockets, and if i open up the torrent app it basically only makes a certain number of connections (like 20, as opposed to 200+ it would make before) and hence "blocks" connections from all other socket-reliant applications, including ftp, http, https and what not.

ANY clue how the heck i got into this pickle? a completely reformatted too, and right now am practically running a barebones machine, haven't even installed anything! NIC is fine i'm sure of it, and i'm connected directly to the network.

any way to increase the number of tcp sockets that XP can make?
 
You said you are in a Dorm?
Did your network administrator change his firewall settings to limit Internet connections?
You can do amazing things with a good firewall.
