Wireless Router loss it's wireless ?

Hey all,

First off, I appreciate everyone whose reading this and hopefully
someone can help me solve this problem. I phoned 1-888-NETGEAR and they
won't let me talk to them because my warranty was over ... how dumb !!

Anyways, I think my Netgear MR814 V1 Wireless Router loss it's
wireless. It has been up and running perfectly fine for ~3 years now
and all of my devices detected it and worked perfectly wirelessly.
However, recently... my other machines and devices don't seem to detect
my router anymore in windows and in netstumbler. Instead, some of my
machines that are within range do detect my neighbors. However, the
computer that are hardwired to the router work perfectly fine. This is
very annoying Ö

I've done the following so far ... yet I still have the problem

- Resetted router ~> held reset button for a minute: while still on
30s/unplugged 30s/plugged back in 30s

- Resetted router back to factory settings ~> in router 192.168.0.1
config

- Tried reflashing to all previous firmwares

- Unscrewed the antenna and screwed it back in (When I shake the
antenna, I do hear sounds)

- Uninstalled WinXP SP2

- Cleaned install Windows on another partition

- - - -

Gosh, I don't know what else I can do. Any suggestion guys ? Or should
I ditch the router and just buy another one? Which would really ****
because I rather spend the money on something else as I am on a tight
budget.

If that is the case, could anyone recommend me a fairly decent 802.11b
router that has amazing range? Also, does anyone happen to have one
lying around they could sell to me or even give away (c'mon guys it's
christmas heeh ^^

Any help would be greatly appreciated!! Also, have a merry christmas
everyone !!

Best regards,
