wireless problem

[Coadman]

I have a D-link DWL-G510 network card in my sons computer. It is approximately 40' from my office computer, where I have a D-link DI-624 wireless router. This is all on the same level in the basement, and is acutally only going through maybe two walls(if you dont count the open doorway to the office). His computer has worked intermittantly, with the dsl service, sometimes he's on, sometimes he's off. I just upgraded him to a new Dell system, and switched the card over, and was surprised that it is the same. I forgot to mention, he hasnt had internet access with his old computer for over a two weeks, and changing to this new Dell didnt help(previously, he had been able to get online, but not on a consistant basis). We always get the message "network cable unplugged", but I know it isnt , the card is in the slot, I even took it out, and reinstalled the driver, etc, plus, unplugged the wireless router, and repowered it, but that didnt help either. So, Im thinking maybe the wireless network card, just quit, and if so, I think Ill go to another brand, as that thing hasnt worked correctly from the word go. Any ideas, or recommendations?
thanks,

Getting a "network cable unplugged" message on a wireless network simply means that the wireless adapter in the computer is not able to communicate with the router. You have already reinstalled the wireless adapter, so the next thing is to determine the actual cause of the problem.

Even if it means disconnecting from the DSL modem temporarily, move the router closer to his PC to see if it can get a signal. If so, then his computer is simply too far away (or has too many obstructions/interference) to get a signal from the router when it is in your office. If it still cannot get a signal when the router is close to the PC, then either the router's wireless capability or the wireless adapter in your son's computer has failed. If you have access to another wireless device you can confirm that the router works and know that the card in his PC is bad. If other wireless systems cannot connect you may need to replace the router.

If you determine that the hardware is working properly and will establish a connection at shorter range, you may be able to make it work by installing high gain or omni-directional antennas on the wireless devices to improve the strength of the signal. Also try moving the router and the PC around so that they are not directly against any walls or other obstructions.

I have the same wireless card in one of my computers at home. It is attached to a Microsoft MN-700 wireless router. I am about 50' from the router with two walls in between and my connection goes up and down all day. Soemtimes it says good, sometimes low, and sometimes fair. Every once in a while it will lower the transfer rate to 36.0 Mbps. I am not impressed with this card at all. I would suggest the same as the Fardingle. Move the router closer to the PC or vice versa and see if you get a better signal. If it works and stays up then try different variations of placement for the router and the PC to get the best results. I have found that the higher the routers antenna are the better coverage area I get. If you still can't get a good signal then I would suggest trying a different card. For desktops I like the cards that have a moveable antenna like the D-Link DWL-AG530. They are a little priceier but I found that being able to move that Antenna around realy works. I have one of these at work on a pc in a converted closet to office situation where no wired connections are available and it works great. This thing is about 150' from my router through umpteen million walls and cubicles and I get a constant 54Mbps!

The solution is simple, you put temporarily the remote computer next to source you configure it correctly to work well and then you move back, if it gets Bad then it is Distance problem.

May be this can Help.
