Troubleshooting Dual Computers with Shared Internet Connection

Click For Summary

Discussion Overview

The discussion revolves around troubleshooting an internet connectivity issue involving two computers connected to the same modem, where one computer is functioning while the other is not. The scope includes technical explanations and potential solutions related to network configurations and hardware setups.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Exploratory

Main Points Raised

  • One participant questions the capability of modems to support multiple computers and requests clarification on the type of extension cord being used.
  • Another participant suggests that the issue might be related to the router and proposes resetting it as a potential solution.
  • Concerns are raised about the possibility of a firewall blocking internet access and the need to check the specific model of the modem being used.
  • There is speculation about whether the absence of a router could be causing the issue, particularly if one computer is connected via Ethernet and the other via USB.
  • Participants discuss the potential impact of software, specifically Norton Systemworks, on internet connectivity.
  • One participant mentions that the Speedtouch device includes a firewall and hub, which could complicate the setup.
  • There are suggestions to consider the length of the USB cord and whether it might be too long for proper connectivity.
  • Participants express uncertainty about the exact nature of the problem and suggest checking for any recent changes in configuration.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the root cause of the issue, with multiple competing views and suggestions remaining throughout the discussion.

Contextual Notes

Limitations include the lack of specific details about the modem model and the exact nature of the extension cord being used. There is also uncertainty regarding the configuration history and whether any recent changes may have affected connectivity.

My friend has a problem. He has a computer that has one working internet and his other computer's internet is down. They are in separate rooms but are connected by an extension cord. They are both connected to the same modem, any ideas why one is working and the other isnt? (They share the same internet connection)

1) I wasn't aware modems (I assume you mean cable or DSL) could support more than one computer.

2) You ought to tell us what kind of "extension cord" you're talking about. USB? Ethernet?

3) You ought to tell us what kind of modem he's using. Surboard? What model?

4) Did this configuration work in the past and then stop working, or is he trying to set it up for the first time?

Something wrong with the router?
 
I'm wondering if he doesn't have a router at all, and is trying to connect two computers to the same modem, one via ethernet and one via USB or something...

- Warren
 
Yeah, it's a DSL.

- A USB cord.

- Speedtouch is all he could find

- It worked in the past, he says.

He's also wondering if Norton Systemworks kills the internet?

Try resetting the router by turning it off for 30 secs, make sure there isn't a firewall blocking your internet access and take a look at the following thread https://www.physicsforums.com/showthread.php?t=37940, maybe it's an electrical problem.


How does he check to try and reset the router by turning it off?
 
Okay so he has some Speedtouch device which includes a firewall and hub along with the modem itself.

Has one of the computers been moved? It's possible his USB cord is too long and is not able to serve the long distance between the PC and modem. Perhaps he should consider using ethernet instead, if his particular Speedtouch device supports it.

Has anything else changed in his configuration? Most problems like this occur when something is moved, upgraded, or re-configured in some way.

Could be, just turn the software off and he'll find out.

I'm not sure what your question was about the router, but modems and routers reset themselves when you take power off of them for 30 secs. It's worth the effort locating both the modem and the router and see what's going on.
