The original people who installed the system (whoever they are) didnt use repeaters, just multiple ap's. Maybe it's more reliable.

i don't think its reliable because you're having issues with dlink. If you still want to go d-link get the new Xtrem-N AP for better signal. But my suggestion get a wrt54gl which is lhaf the price of the dlink router and flash it with dd-wrt and make it a repeater.
here's the link from compusa for the 2 products:
D-Link Xtrem-N:

Linksys WRT54GL:
http://www.compusa.com/pro
Honestly, its all about experiences. Personally I'll never buy a Linksys ever again. Have had horendous luck with the WRT54G's (various version from 2 to 6). I swear by Netgear now for SOHO APs. Personally I'd stay with what you have until you are reasonably sure its the APs that don't work or else you could be wasting a lot of money. Do not go with repeaters though unless you have low numbers of users using the APs. Otherwise you'll just saturate the AP bandwidth; remember wireless is comparable to hub technology, the antenna can only communicate with one host at a time.
First, what are the channels you are using, sounds like you have 4 floors. Place each floor on a different channel: 1, 4, 8, 11. That should help ensure they don't interfere with one another.
Second, you say you have range problem. Can you be more specific? How far away are you from AP, what materials (e.g. walls, microwaves, water bins, glass etc.) are between you and the AP.
Third, what are the floors made of. Are they cement, if so no waves will leak thru, but if their wood, try moving where the APs are positioned so Aps on different floors could cover "dark" areas of other floors.
One thing I would recommend is getting a decent PCMCIA wireless card with good software. What you're looking for is something that will give you information like the MAC of the AP your connected to, the SNR, etc. This will help guide you in knowing where high AP roaming occurs and signal ability. Signal strength should be atleast -70dB and SNR should be at least 15 to 20 dB for a quality enough signal to be useable.
Just out of curiousity, what info is missing that you gave this a grade of B. I thought it was a fairly complete answer on what can cause poor ranges and how to test out your wireless infrastructure to see if it suffices. so just wondering why you're not considering it a complete solution when there was no additional followup

why not use linksys products both for router and repeater base on experience they work much much better than dlink products. btw what's the distance of your office veertical and horizontal maybe you need more repeater
linksys WRT54G - for the router
linksys WRE54G - for the repeaters
