2nd PC on network killing my Internet (help)

[unozero]

I have Verizon fios and I'm going from the router directly with a Ethernet cable to my PC.In the other room there is another PC that my Uncle and my little Sister sometime use-It uses a wireless USB adapter.When ever that PC is connected to the Internet my connection dies for no good reason every couple of minutes ,I'd be loading a page and eventually FF will say "connection reset."
Every time I click on diagnose problems Windows finds nothing I wait a few seconds then it will start working again.....Anybody know how to fix this???

When that computer is on and you try to ping something what response time do you get? How does it compare to when the comptuer is off?

To do a ping test go to command prompt and type ping yahoo.com

I had this problem with my sister's computer, turns out it had viruses. After a clean, it was fine.

try cfosspeed, it regulates packets and shit, letting you use internet more efficiently.

Thx guys gonna try that ping thing first.

Your sister, or her computer?

(Sorry)

Maybe you should use a router with a switch. What router do you use?

The one they provided us with...I mean as long as the other PC is off I NEVER have problems but my little sister got kicked out of her mothers house so she's living me for a while that means this issue will be even more annoying.

It could be that they have a virus. Just do a ping test and it should tell you if they are generating a large amount of traffic.

A router has a switch built in to it, there is no point of adding a switch if you don't need an extension of the ports.

Didn't think of your sister as a fan of pornography.

I think you're mistaken. Not all routers have switches to route traffic. In fact, only 1 of the 4 routers I own has a switch. Without the switch, all packets go to all computers, it's just a matter of which computer is expecting and accepting them. This is how I understand it anyway.

Just like not all routers can be used as a crossover either.

Your model, unozero:

Integrated Wired Networking with 4 Port 10/100 Mbps Ethernet Switch,MoCA and/or HPNA 3.x.

I'm not sure if that means it has a wireless switch as well, however.

wired Ethernet broadband routers typically incorporate a built-in Ethernet switch. These routers allow several hubs or switches to be connected to them, as a means to expand the local network to accomodate more Ethernet devices.

Really, it's a feature usually reserved for more expensive models, in my experience.

Oh, here's something I did not know:

In home networking, hubs and switches technically exist only for wired networks. Wi-Fi wireless routers incorporate a built-in access point that is roughly equivalent to a wired switch.

It's not a big deal if a router doesn't have a switch. That just means the extra ports are a hub. The only time a router is just a router is when it only has 2 ports (1 to PC and 1 to modem).
A switch and hub are basically the same thing except one is more efficient. But that shouldn't cause a signal issue especially with only 2 PCs on the network. I remember sharing an internet connection back in college. 4 students and a 4 port 10mbps hub. Worked awesome dling and gaming. Although never had wifi in the mix.

I'm going to guess it is either how it has been setup or the router/modem itself. I know some modem/router combos they give out are not the best and have issues when that same config. would be simple for a normal off the shelf modem from dlink or linksys.
Do the IPs of your computers have the same number except the last digit? Are they in order like 192.168.254.2 and 192.168.254.3? Is the wifi encrypted (WPA2-PSK)? Is your model the Actiontec MI424WR? Check this.

I have a wired modem and router all-in-one that the DSL company gave but I neutered the router. Have a linksys setup instead with the settings the other box normally would have to connect to the DSL through the modem.
So the linksys has the login and ports or whatever is needed to connect to my dsl.

Any router post 20th century will have a switch instead of a hub if it has more than 1 port for the LAN. Hubs are repeaters that send packets out to everyone where a switch uses some intelligence when dealing with the packets giving you a lot more efficiency. The reason you would go with a hub back in the day was because of the cheaper cost, this isn't longer an issue and hasn't been for almost a decade. There are some very minor exceptions to this but they aren't even worth mentioning here.

Look up what a router actually does then look up what a switch does to get a better understanding of how they work together and what their functions actually are.
