 Alert | | Just looking for ideas. I have a wireless network set up using a netgear router. The computer in my kids room is about 15 feet away and gets a horrible signal. Most of the time it just loses connection after a few minutes. Think I should try a different router? Maybe linksys? Im using a budget wireless pci card also. Maybe I should switch to a desktop usb wireless thingamajigger. Im tihnking router because I can actually use the laptop downstairs with decent connection. Suggestions? | |

Alert | | Actually one way to eliminate interference is to change the channel on the router. If you have baby monitors, cordless phones, or home scurity systems witinh wireless cameras all of thse fucntion on the same 2.4ghz range as your wireless router. If you can access the GUI change the channel to 6 or 10. these are non interfering channels. You should eliminate that interference. Also be wary of anythign with a electric current running through it. This can cause EMI interference. | | | |

Alert | Also try channel 1. Like TJ was saying they're the only truly unique channels, all the rest are overlapping. If you post your router's model and version number, we can look it up and see if there is a firmware update available.
Are you using XP SP2? When was the last time you ran Windows Update? What wireless card are you using (so we can check for driver updates)? | |

Alert | I highly suggest paying a bit more for a good Wireless NIC card. Believe it or not, that's usually the problem when having major interference issues. But what Jason and TJ say is also very good advice.

Alert | i'm currently using netgear router, from what i heard, netgear sux!! and i believed it. i do get alot of interference, then again my cordless phone knocks out the signal each time the phone is in use. | |
i don't like people who uses "signature" on their profile. TAKE IT OFF!!! | |

Alert | | The cordless phone knocking out your wireless portion of the router would happen on any wireless router that has the same frequency as the cordless phone. Most wireless routers run on the 2.4 ghz signal and cordless phones running on the same signal will interfere with the wireless router. Best to get a cordless phone not on the 2.4 ghz frequency or same frequency as your wireless router | | | |

Every router that I hknow of has the possibility of changing the channel to one of three non interfering channels. Why spend more money for a new phone when its easily fixed? | | | |

Alert | Also, it makes sense to note that for some reason no matter how much you spend on your internal PCI wireless card, most laptop wireless cards are going to be more powerful. Not sure why. its just a fact.
QAlso, I have a 19 dollar PCI card I bought on newegg.com in my computer and my router is 75 feet away. I have five out of five bars in signal strength right now. SO budget wireless cards can work. | | | |

Most 2.4Ghz cordless phones are spread-spectrum, meaning they hop frequencies while in use, rendering your wireless connection useless. Even for the ones that aren't, they pick a new channel every time you make a call, so there is going to be a collision sooner or later. | |

Alert | BUT. Out of the 11 - 13 channels available on the 2.4 ghz range. Channels 1,6, and 10 are non interfering. Meaning 2.4ghz phones will not utilize those channels. | | | |

Alert | Actually, no.
Most 2.4GHz phones use frequency hopping spread spectrum (FHSS) technology that operates within the 2.4GHz spectrum. FHSS hops from frequency-to-frequency across the entire 2.4GHz spectrum. 802.11b WLANs, on the other hand, use direct sequence spread spectrum (DSSS), which transmits within approximately one third of the 2.4 GHz spectrum. Because FHSS jumps across the entire spectrum while DSSS stays in only one portion, a FHSS 2.4GHz will clobber an 802.11b network, causing interference or even failure.
<a href="http://www.wi-fiplanet.com/tutorials/article.php/2191241">Source.</a>
So if you (or a neighbor) have a FHSS cordless phone, your network is hosed, no matter which channel you set it on. 1, 6 and <b>11</b> are the only unique channels on the spectrum, which means that if you have a neighbor with a router on channel 6, picking 1 and 11 will prevent any interference from another routers that are hopping through their 1/3 of the spectrum.
Incidentally, this is also why non-FHSS cordless phones can cause interference. Say your router is on channel 11. You pick up the phone and make a call. Your phone picks channel 3. Next call it picks, say, 1. Eventually it's going to pick 11, wreaking havoc on your wireless connection. | |

Alert | Jason,
I don't know of anyone else on here realizes but you really just sortof showed a bit of ignorance. You refer to the 802.11b networks as if they are the standard, when for almost two maybe three years now the G network has been the standard. The G network functions on the same spectrum and is less likely to have crossover interference and is likely to utilize the entire spectrum. Simple way to solve this problem is if your router had the capability of choosing b/g networks or simply choosing to set it to g only networks then voila the spectrum interference is gone.
Most of the individuals here I can GUARANTEE you purchased a "wireless G router" for use and it will have this capbility.
PizzaKing, I would be more than happy to take a look at your network and see if I can come up with a solution for you. Frankly, this debate has gotten worn out, and even boring to me now. a 2.4 ghz phone is quite capable of functioning in the same locale as a wireless router if it is configured correctly. Dont waste your money on a new phone system yet. Oh and did anyone mention that even 900MHZ cordless phones can cause issues? | | | |

Alert | Just a comment here.
I had a b/g Netgear router, and my 2.4ghz phone definitly caused interference. It would kick off all my machines (all 11g) whenever the phone rang. I ended up replacing the phone with 900Mhz (before 5.4ghz was available)..
I've since replaced the router, but haven't tried that phone again yet. That phone also had issues with the microwave (would drop calls if you were standing next to the mic and using it..)

I showed no ignorance, and did not refer to 11b as the standard. The article demonstrated using 11b, but the same applies to 11g. 11b and 11g are functionally the same as far as interference from other 2.4Ghz devices go. They both use DSSS, which covers 1/3 of the 2.4Ghz band. So if you have a FHSS cordless phone it doesn't matter if you have an 11b or 11g network, they will both get interference from the phone. If you don't believe me, please look up the specification.

The <i>only</i> way a 900Mhz phone could cause problems for a 2.4Ghz wireless network is if the phone is really messed up. | |

Alert | | Hmm I tried different frequencies but still didn't have any luck so just spent the money on a 5.8 GHZ and problem solved. | | | |
