yet another "limited or no connectivity" issue

Ok, heres my situation. I have been running my computer of of a net gear router for the past year or so now, but, for gaming reason, I decided I wanted to bipass the router. I did this by purchasing an ethernet hub and running this setup: modem connects to the hub, then the router and my computer connect to the modem through the hub, then my brothers/ dads computers run off of the router. Well, the router still works perfectly connected through the hub, and both othre computers clock normal bandwidth speeds ( ~4 megs/ sec ). However, my computer ( running straight off the hub ) gets "limited or no connectivity ". When I plug my computer into the router I get internet. Back to the hub- "limited or no connectivity "

This is not just an error caused by sp2, becasue I have no problems running through my router. I have reset my modem, hub, and router many times with still the same result. I am going out of my mind here. Any idias on how to get this to work?
Thanks,
Riley

P.S disregard any spelling errors =p

 

As you describe your new setup, you should see either the router (which is probably a router/switch with NAT and a couple other essential features) or the stand-alone PC able to connect to the internet and the other device not. I think that if you either power off the router or dissconnect it and reboot the PC connected directly to the hub (errr, probably a switch) that it will connect fine and the router /w PCs will not.

Depending on how your ISP is set up, it may be that only a single device with a MAC (hardware) address known to the ISP will be allowed to connect to the internet and in that case, your PC on the hub won't even if it's first.

Bottom line though, unless you rent two IP addresses from the ISP, you can't run the way you are trying to.

Assuming your isolated PC is running NT (NT4/2K/XP/2K3), open a cmd prompt and key in

Code:

ipconfig /all

If you see an IP address beginning with 169, the PC was absolutely unable to find any device willing to assign it an IP address and just made one up to allow the PC to start.

You can probably do what you wanted when you added the hub by putting your PC in the DMZ if the router has a firewall and offers that feature. You do bypass firewall protection though.

 

1st a question.
Why do you want to by-pass the Router ?

2nd a thought. If you are using a HUB that might be the problem. I believe you should be using a Switch.

Newt can more than likely expand on that thought.

3rd another question.
Do you mean Internet gaming or LAN gaming ? We use both and no problems.

I have three machines and a printer plugged into a 4 port SWITCH then the Switch is connected to the Router. And the Router and Modem are of course connected and no problems whatsoever.

We play Golf with a Friend in Canada on Tuesday Evening. My wife and I are always playing games between two of the machines.

sorry bout that. Yeah, it's a switch. The only reason I wanted to bipass the router is that ( on occasion ) my bandwhidth speed drops horrendiosly to <200k/s. If I plugged my computer into the modem, it would go back to 4k or watever it was before. I also have no clue how to open ports on the router, and didnt want to have to deal with all that fun stuff. Also, what did you meen by the DMZ on the router? is that a certain plug or what? I am a complete noob when it comes to networking so please, bear with me.

 

DMZ - can be a seperate plug or can be firewall settings depending on your device. No need to get into gory detail unless it looks like you need it. Basically, just like in Korea, it's a very unsafe buffer zone.

As to the rest, it will help if you give specifics on your network cards, router/switch, switch including the brand name and model number. For instance, I run a Linksys BEFSR41 router/switch and with that information, you could easily figure out what features is has and which one it lacks.
