the DD-WRT firmware on a Linksys (or other compatible router) is extremely compatible with OS/2....never ever had an issue, and I've run this type of hardware firmware for many years now - long enough to 'burn out' the router since I overdrive the transmitter by 200%. I run an average of 500-700GBytes per month through mine. OS/2 did not report the PC's name in the way the router expected (which only led to a blank name in the client table the router served addresses and DNS perfectly). I believe it took an optional statement in the tcpip.config file to have the 'name' show up in the client table on the router.  The router and firmware is totally compatible with DOCSIS and all PPoE variants, PPTP, L2TP etc.  DD-WRT works with all dynamic client services, too. Preconfigured for Dyndns, freedns, zoneEdit, no-ip, 3322.org <http://3322.org>, easyDNS, TZO, DynSIP and you can configure a custom ddns service too. Overclocked it will handle a 27mb wan connection with the SPI firewall turned on, and about 30mb with the spi turned off and safely fanless overclock to 250mHz.
