-The WRTU54-TM has an 8MB flash, 64MB RAM, Infineon WildPass ADM8668 SoC, Infineon Vinetic device for the two telephone ports, and GemPlus GemCore SIM Pro Smart Card Reader attached to the USB bus to read credentials from two SIM cards.

The wireless chipset is a Ralink RT61 on the PCI bus. It utilizes UMA/GAN. Basically all voice traffic is passed as GSM over an IPSec link to T-Mobile.

 +Most information was scraped from [[http://www.dslreports.com/forum/r21597694-Unlock-Unlock-tmobile-HiPort-router-|dslreports thread]] and sn9's [[http://openwrt.org/logs/openwrt-devel.log.20081006|openwrt irc log]].

 +====== Throughput ====== 
 + 
 +Using [[http://wrt.scottn.us/wrtu54g-tm-r26444.bin|Alex's Firmware]] (mine! LOL) with a fairly basic firewall config, wireless disabled and connected to a BT FTTC connection via the BT Openreach supplied modem with an IP Profile of 23M, the device can put through approx 18Mb/sec, but this can have the serious effect of blocking PPP echos, so editing /etc/ppp/options is required to relax the somewhat strict OpenWRT defaults. This will cause the device to disconnect less frequently. 
 + 
 +Unless something magical happens, I doubt that this 200Mhz device is up to a connection much above 15Mb without it becoming a bottleneck.
