Internet Problems

[purdueman]

I have 2 computers on a network and i access the internet through a router connected to a modem. Just today my internet connection got screwed up, and i had no idea how, so i reset both Comps, Router, and Modem. When i got back on my Main Comp for gaming (World of Warcraft) my ping levels were at 7000ms!! and viewing webpages didnt work.

My comp said both my connections LAN 1, LAN 2 said they were disconnected, but they were not. So i tried a different cable. It said it was connected but i couldnt access anything on the internet or on my network but i could see my folders from other comp but could NOT access the folders through my network and vice versa. Meanwhile on my other Comp i could access the internet.

If anyone has any suggestions on how to fix my Internet Problem with my Comp it would be much appreciated!

Can you tell me exactly how your network is setup?

Both the Comps are connected to a router which is connected to a modem ( i have cable internet) For a little bit yesterday it was working but then i put another LAN in(2 ethernet ports) which i always do and it stopped working.

With both machines turned on, go to Start,Run and type cmd hit enter. At the command line type ipconfig /all and hit enter. What are the IP Address,Subnet Mask and Default Gateway of the Ethernet Adapter Local Area Connection of each machine? There is a setting that says DHCP enabled ........yes or no. Are both set to yes? Do

Both machines output should be identical except for the IP address Physical address .

7000 ms is way too high. I can imagine a lot of timeouts occurring in between. Normally, ping replies are below 400 ms to be able to get a decent response from most applications you are accessing from the web. Since you mentioned that you recently plugged in an additional computer, here is my suggestion as to how to address the issue:

(1) Lets call the 2 computers A and B where B is the additional computer. If I understand it correctly, your Internet connection screwed up after B was connected.
I assume that your router has built in ethernet ports - much like a switch. *** I suspect that computer B has spyware/virus that persistently connects to the Internet and sending bulk data, causing your bandwidth to be exhausted. Thus slowing response time. Who knows? It may even have affected computer A. ***

(2) Disconnect the LAN cable of computer B from the LAN and leave A connected - this should be your original setup that is in working condition. Reboot the modem, router, and computer A. ***Hopefully, this works***

(3) If it still does not work, use a third computer, say computer C (notebook/portable computer) which is known to work from another Internet connection. Disconnect all LAN cables of A and B from the router. Plug computer C in your network and see if you can connect to the net without problems. If you can, then you need fix computers A and B (probably an anti-virus cleanup, system recovery or worst case - reformat :( ) as computers A and B have been affected by virus/spyware. ***If problem persists, proceed to next step***

(4)With only portable computer C connected to the router C-->router-->modem-->Internet , try to a continuous ping on www.google.com (i.e. c:\ping www.google.com -t). Observe if the response time is still high. If it is, either the router or your cable ISP is at fault.

(5)Bypass the router by directly connecting computer C to the modem c-->modem-->Internet. Note that at this point, you are no longer obtaining an IP address from your router BUT from your ISP directly. In short, PC C is the one taking the place of the router as far as authentication goes. Normally, they require you to key in your username and password using PPPoE and once you are authenticated, you are connected. The other common setup is your ISP issues you an IP address which you key in manually or just obtain an IP address from them. Whatever the setup is, for this step, it is best to coordinate the settings with your cable ISP. ***If the connection speed improves, then there is a problem with your router. If the connection remains to be slow, its time to refer the problem to your cable ISP.
