Here is my setup. I am in a 3-story (basement, 1st fl and 2nd fl) condo. WRT54G WAN port connected to cable modem in basement (stuffed behind ceiling tile) All phone wiring is CAT5-enabled (home builder feature) so all phone jacks are connected back to a central console in the basement. So some pre-designated phone jacks can be connected to the router by plugging in the corresponding cable into the numbered port behind the WRT54G. Basement has a PC with a wireless USB Linksys adapter (less than 10 feet from the router in the ceiling). PC #1 Bedroom 1 on the 2nd floor has such a wired connection to the router. PC #2 Bedroom 1 on the 2nd floor has a unused RJ45 connected to the router. #3 A laptop floats around the house. #4. #2 works great, obviously. #1 works most of the time but connection sometimes drops during use (annoying but nothing a power off/on of the router doesn't cure) Ditto for #4. But #4 is used (mostly) by the wife so it is in my best interest to address it. What is the problem? Is the wifi signal not strong enough to reach all round the condo? I tried getting one of those long antenna thingys (from CompUSA) to replace the antenna on the router but that didn't help. I know the WRT54G I have is one of the "crippled" ones (with small amount of RAM). So I was thinking of replacing it with the WRT54GL (Linux), hoping that my problems magically go away. Will they? If they don't, I was thinking of using the current WRT54G (which will be unused after I buy the WRT54GL) as an access point on the 2nd floor by plugging into the unused RJ45 in #3 (not sure I need a special crossover cable for this or a regular Cat5 will do) Any thoughts, suggestions, comments greatly appreciated. Thanks.
