    We do have other wireless items (phone, hifi speakers). I'll share this info with my husband and see if he agrees that re-setting the router might be the solution.

    Thank you,

    Problem finally solved! It was so simple, it's embarrassing to relate. I called HP Customer Service AGAIN (1st time they couldn't solve the problem) and it turns out there is a teeny tiny switch on the front (left side) of the computer. Every time I handled or cleaned the computer (with an alcohol swab) I was inadvertently turning this switch on and off. For wireless to work, the switch has to be slid to the right (a blue light comes on). Even my husband, who used to build computers, never noticed this switch. Nor is the switch evident when I looked at any diagrams of the set up on the HP. Anyway, I really appreciate your help. I've been out of town and neglected to get back to you. My apology. This solution reminds me of the times I would call my Help Desk at work to say my computer wouldn't work and they'd ask, is it plugged in? Once it turned out that the night cleaning crew had indeed knocked the plug out from the wall! Thanks again. Love this site -- you were prompt and helpful.

There are many reasons that the signal can vary from place to place and can change drastically just inches away.
a few sources for interference are:

  • cordless phones
  • baby monitors
  • basically anything wireless
You see some of the above work at 2.4 ghz frequency and can block and distort data coming from your router to your pc.Luckily there are quick fixes that sometimes work for instance:
  • setting your router to another channel:
You can do this by going into your routers wireless settings and changing the transmit channel from say 1 to 2 and so on and try that for a bit.
How do I get to the router settings you ask? Good question, well its pretty simple but it varies greatly from router to router so you will have to look in your manual that you threw away when you bought it :) or just check on the internet and search for "(make and model) settings" at the product website.

if you'd rather provide the make and model here id be happy to search for you and find out how you can configure your router.
That said my main suggestion is to get an Ethernet wire to that stationary pc, it will surf a whole lot faster unless the wires are a pain. Most home wireless speeds pale in comparison to hooking directly up to that same network.

My computer won't work with wifi at my house but it will work everywhere else. Also other laptops work with the wifi at my house but mine doesn't. How do I fix this?

I'm assuming it's a laptop and not a desktop. Check the wireless Network connections and verify it is enabled. Check to see if it picks up all the surrounding networks in your area. Check your wireless switch to verify it's on if you have one. Make sure you input the correct "access code" to your router or modem to get the wireless. Try to disconnect from the SSID and reconnect with the known correct number again.

I only have one PC in my house and it's not in the same room where the cable outlet is located. Right now I have a very long coax cable running from my cable modem to the cable outlet in the other room. Is...

Purchase either a USB stick that adds wireless capability to your laptop/desktop, or purchase a PCI wireless adapter-card for your desktop, and install it.

Then, you can move the cable-modem much closer to the cable-outlet, and then connect the cable-modem to a newly-purchased wireless-router ($20 to $70) to receive/transmit over your in-home wireless network.

Toshiba laptop just purchased does not recognize UM 150 even though driver has been installed on computer. What is the problem?

You are referring to the Verizon wireless modem?
And what is the operating system?

In Windows you can check the device manager to see if the device is working and if the driver is installed.
If you plug it, you should at least see a device in the "Unknown" category. You can right click it and see what the error is. Try to install the drivers from there by specifying the driver location.

There are more causes for usb device not recognized problems.

Dell dimension 2400, wireless internet

Hi Whitney,

I was able to locate manual and a troubleshooting guide.
  1. Manual
  2. Troubleshooting Guide
Summary: Your modem only supports 802.11b standard, which limits the throughput to max. 11Mbps (compare to 802.11g = 54Mbps, 802.11n = 108 Mbps). In other words: your connection is only about 10% of the speed compared to a wired connection via Ethernet cable (100 Mbps). So - if you can - you should try to use a wired instead of a wireless connection, but you have to decide what makes is more important to you: having no cable and you can be away from the modem or the connection speed.

This also means - and that is in regards to APremkumar's solution - that you can skip all 802.11n adapters (this would just be a waste of money). Since you will not find an adapter that only connects to a class b network, look for something like "802.11b/g".
An example page is here. You can choose between an internal (PCI card) or external (USB adapter) solution. Both are ok and the decision depends on the availablity of a free USB port on your Dell and your comfort of opening the computer case or not. (You can always come back here and ask for help;-)

If you have any more questions, please let me know - I'm happy to help!

Belkin wireless adapter

Sometimes wireless phones will interfere with the signals. If the router or PC is anywhere near a phone, it might have a problem. I have one wireless network card that gives me fits like that. I have yet to get a PC working with it. I have other wireless cards that work fine. I also switched to 5GHz phones, which helped my old laptop. Check to make sure there's not a conflict with the encryption used by either the dell or the router.

Wireless connection problem, I have a gateway T1631 laptop. I cant see any network within the range even though I place d next to the router, but I can connect to the internet through the ethernet drive.

I have seen this issue alot of times. Please make sure you wireless card is turned on. Sometimes the switch is on the front or the sides or you may have to push a function button + a wireless button. Take a look at you owners manual to be sure

One of the laptops we are using on the wireless modem/router is not detecting the modem even though it has been installed as instructions, whilst the second laptop that we installed the adapter onto is...

Let me make sure I understand the issue. You have a wireless adapter that works on one laptop but not the other? If so, blow out the card slot on the defective one with compressed air. Make sure it's firmly in place while the machine is off. So when it's clean and firmly in place, now turn it on. It should recognize and come right up.

If not, you may have to reinstall the device. I mean the actual slot. remove the wireless card, Right click on my computer and hit properties. Hardware tab, then device manager. Find the PCI slot in the list and delete it. reboot the laptop and it will automatically reinstall the slot. after it says your new device has been installed and is ready to use, put the wireless card in and it should work.

Belkin Wireless Modem Router problem

well, first of all the i also have the N1 belkin wireless modem router, in order for it to connect, there has to be a wireless connection in your area for you to connect to, if any of your neighbors so have wireless you can connect to their network, but if you are not getting a conection that means no one around you has wireless or lan, the belkin wireless is not a internet provider it just extends the distance of your internal wireless. some networks may be secured as well, sometimes you can only connect to unsecured networks unless you have the name and passcode for the secured network.

My toshiba computer does not work with my wireless internet

what brand of wireless modem you have, what os are you using?did you switch on the wireless in your laptop? sometimes we overlook the most simple things, it happens to me..
ok, you have to configure your laptop to connect to your wireless modem, how? just connect first your laptop with wire to the wireless modem, does it work? if it does work you can take the default gateway ip add from your pc by typing IPCONFIG on the command prompt , then type it in your internet explorer address bar.

example default gateway.....

and supply the username and password, you can now configure your wireless connection wep/wpa configuration.
