The network in my office is using a crappy free gateway, similar to those used for home. However, there are at least 10 employees in the office and all the desktops and laptops are using WIFI due to lack of Ethernet cabling. Each employee has a smartphone too, which doubles the device count. What I have done for the past 2 years was to use a spare WRT54GV2 router as second wireless AP so the WIFI load is spread on two different WIFI networks. However recently the router as been acting up. Being the "computer guy" I've been put in charge of upgrading the office network. I have no experience in doing this kind of stuff and the amount of information is overwhelming. My experience so far is just doing simple stuff like assigning fixed DHCP IP address to the NAS/Printer and changing settings via webconfig. At the moment it seems to me that I will need a small business router/gateway device and some wireless APs. Also maybe upgrade the wifi adapters on the desktops to wireless N.
