I seem to have a very odd situation. I have a desktop computer with no wireless function which "interferes" with the home router whenever it is turned on. This occurs even when there is no wired connection.
The router drops offline and tries to reconnect continuously whenever the desktop is switched on, regardless of whether it is connected to the desktop via ethernet.
All wireless drivers and software have been deleted and uninstalled off the desktop.
I have tried everything i can possibly think of, if you have any suggestions please do post below and i will reply ASAP.
The router and computer are 7m away from each other as well as being in different rooms (blocked by 2 doors and walls).
Thanks! |

| Sounds more like a problem with your electrical wiring. Try running them from different outlets or separate circuits if possible. |

Just tried, no success unfortunately.
I also just tested to see when exactly the internet is dropped, it happens before windows has even loaded, therefore i imagine it has to be hardware side? Does anyone have any idea what it might be? |

Sounds like radiation emitting from your computer thus cancelling some of the wireless waves.
But wait....an electromagnetic wave generated from an ordinary PC cant be that powerful.... |

| Are you using an UPS ? ( PC and router on the same UPS?) |

I don't know what that is, could you expand on what you mean? |

I would suggest running a control test. It may be hard to find the same router but ideally you would want to try with a different but identical router in a sterile environment (aka not your place but somewhere known to have proper electrical wiring) to see if it still causes the interference. If you have a friend with a different router you could test for intereference using a different router too.
It may also be a good idea to contact the router manufacturer and see if anyone else has ran into an issue like this. If it is EM radiation coming off the PC you can always make a Faraday Cage for your PC.
Last thought, have you tried starting the PC without the ethernet cord plugged into the router?
Sorry if my thoughts have been all over the place still working on my first coffee this AM, but goodluck and I hope you post back with your findings or fixes. 8D
Edit: Im thinking about the posibility that its a wiring issue in your house, bad grounds or no grounds for that matter is the only thing I can think of but I would think the PC and router would have to be on the same circuit. You can buy a tester at Home Depot or even Wal Mart I think to check if the outlets are wired correctly.Last edit: 2012-08-12 22:39:10 |

Yes, i've tried it with it connected and without. It's definitely something wrong with the desktop itself as the other computer works 100% perfectly while the other is off, so i don't think it's the router as it was replaced only 3 weeks ago.

I've tested all the sockets in my room to no avail, i really don't think it's a wiring issue as it hasn't always been a problemLast edit: 2012-08-12 22:56:13 |

Crazy stuff. This is such a weird issue, is the problem PC an old PC and are you running the two PCs near eachother?
Edit: Another thought, you said you uninstalled drivers etc for wireless on problem PC; I assume that at one point it had a wireless card or something, did you remove the wireless hardware from the PC as well?Last edit: 2012-08-12 22:46:43 |

Fairly old (4-6 years), the motherboard CPU and GPU are all fairly recent however (2-3 years).
The PC that works fine is right next to the router, however the one that is causing the problem is about 10 metres away in a different room. Some other people on another forum had some ideas about the PSU and some "electromagnetic noise" or something like that.
*edit to your edit: no, it never had a network card, but it did have a wireless adapter. At least, i don't believe it has a wireless card :D.Last edit: 2012-08-12 22:48:36 |

| Jeez such a crazy issue! With all of this to light, I'd have to agree its definetly electromagnetic noise of some kind, and I think the only component in a PC that could produce that much of an EM field would be the power supply...I personally would build a Faraday Cage to contain the EM radiation coming from the PC, not sure what mesh size you'd need, I've lost too many brain cells since Uni physics classes, but it may be cheaper to just replace your PSU. Once again though GL GL hope you figure it out ^_^ |

Do you have a 2.4GHz CPU by any chance?
Normally with interference problems you're looking for something that operates at a frequency close to that of the wireless signal, or a close multiple. PSUs don't normally get anywhere near that. Note that PCs are supposed to have a faraday cage, but then people have daft things like transparent side panels.
Changing the wireless channel may help.

No, it's 2.66.
How do you change the wireless channel? |

It's router-specific. Normally fairly easy to find in the wireless config section, although N stuff can be a bit confusing.
I'm assuming that you know how to access your router's config.

here are the two most common addresses for that
http://191.168.1.1/
http://191.168.1.254/
these aren't real webpages, it's a webpage on your router itself to run the config options
if neither of those work throw the model of your router into google and see what happens. most routers are linksys so the first one should workLast edit: 2012-08-13 02:20:20 |

At some point there it should have been obvious that you need to specify your router model.
Still, general recipe for router config access in Vista/7:
1. Hit start button, type cmd in search box, return.
2. Type ipconfig, return. Find the "default gateway" IPv4 address for the adapter connected to your router.
3. Type this IP address into a web browser. Should come up with user/pass box.
User is usually admin or something ISP-specific. Password is often admin or password, or may be written on the router.

My father doesn't want me to change anything because he thinks it will mess things up, so i guess that isn't something i can check. Are you sure it's definitely not the PSU? With my limited tech experience it does make a lot of sense, as it is very old ( 6-8 years). What would changing the wireless channel do? I'm on a wired connection....
My router is a Sky model, not sure on anything else other than that.. |
