I have a new Netgear wireless router and comcast high speed hooked up to two computers and one laptop. Everything was fine for a few weeks and know somedays it fine and others when I am on line it throws the two computers off both computers off line. Other days it is fine in the morning and then in the afternoon it starts throwing us off and on the rest of the day. This only happens when the main computer is online. Please help! I have the main computer netgear wirless-G PCI adapter should I not since it is connected to the router and modem? Could this be the problem? I'm confused.I need this fixed asap due to I need my computer all day long to look for a job. I also have had the Comcast desktop docter fix the problem for a short time but it allways go back to the same problem.

Hi Snow,

Let me get a little clarification to better understand the problem. I'm going to list the facts as I see it below and just let me know if I am correct with the below:

• Network Configuration = Cable from the wall to the Comcast Modem then from the Modem to your Router then from your Router to your computers.
• The Internet works fine until one specific computer is plugged into the Router
• The main computer uses a Netgear Wirless-G PCI Adapter, which is just basically a wireless card to connect to the wireless Router

If the above is true please clarify when you said the following:

I have the main computer netgear wirless-G PCI adapter should I not since it is connected to the router and modem

Are you saying it's connected to the Router via wireless and plugged directly into the Modem via an Ethernet Cable?

Once you clarify all of the above I can better assist you.

[snowgypsy]

Yes you are correct on all

Okay great.

First of all on the main computer ONLY connect it to the router or the modem. Do not connect it to both. The network should be connected as follows:

- = Comcast Cable
-> = Network Cable
~ = Wireless
[M] = Main Computer
[S] = Second Computer
® = Router
(M) = Modem

Verify Modem and Router Connection
- (M) -> ®

Ideal Computer Configurations
® -> [M]
|-> [S]

Of course any of the network cables for the computers could be replaced by wireless
® ~ [M]
|~ [S]


Once one of the above optimal configurations is in place please let me know if the same problem is occuring and if both machines can get online.

Lol and sorry my routers become copyright symbols and shrank a bit. I basically was just trying to create some visual aid though. Again like I said above make sure the comcast cable goes to the modem, an ethernet cable goes from the modem to the router, and then the computers connect only directly to the router via either Ethernet or Wireless.

[snowgypsy]

No problem. So the main computer does not need the wireless adapter and I can take it back to the store right? Only the second comput and laptop needs it right? Also the main computer since it is hooked up to the modem and router so I should hook to Ethernet?

[snowgypsy]

And I should remove the wireless adapter software on the main computer after I removethe adapter right?

The main computer does not need the wireless adapter if it has an ethernet port and cable close enough to the router. The laptop needs the wireless if you want to walk around and have access to the internet.

How is the main computer hooked to both? Does it have 2 Ethernet ports or you're saying it's connected to the router with wireless and the modem with an ethernet cable?

[snowgypsy]

The main computer was hooked up with a wirless adapeter and wirless router & modem with the ethernet pluged from the modem to the router but I now removed the wireless-G PCI adapter. Is that all I need to do or do I have to set up the whole network again?

[Untalented]

Okay so now just plug your main computer into the router and not the modem. The router should have 1 cable from the WAN port going to the modem.

Then test the Internet on both machines and verify all is working.

[snowgypsy]

The main computer allways has the connection from the computer to the router and the wireless router & modem with the ethernet plugged from the modem to the router. But the second computer is still losing the connection three times in ten minutes and know both the main and second computer (wireless) one was disconnected too. below is a message logged from min. Please help!!

Okay so now your main computer connects directly to your router and not the modem though right?

If you unplug your main computer from the router does the laptop start working again and have no problem?

[snowgypsy]

Yes, the main computer is only hooked into the router. I unplugged tthe main computer from the router and the laptop and the second computer still works. Why is it when I'm on the main computer it is fine for hours sometime and then we all get thrown off the internet on and off? Do I need to go to "Network connections" in my control panel and change it or something?

I also noticed when I had aol dialup I had the telephone line hooked into my computer. Now that I have Comcast high speed the tech left the telephone line hooked into the computer. Could that cause a problem since I unplugged it for a while and we were all still connected to the internet?:

DISREGARD THIS POST, I FOUND THE TELEPHE WIRE WAS HOOKED TO MY COMPUTER BUT WAS NOT PLUGGED INTO THE WALL. SO I JUST UN PLUGGED FROM COMPUTER ANYWAS. SOORY
