SWART2-54125 with TNETW1130, previously using T360C.060208a2_04 firmware.
Problems with router freezing, needing a reboot, and having to disconnect and re-connect devices to get them to work.
I uploaded annexB using the web interface, which went fine but DSL did not work, claiming the carrier was down.
Tried the RouterTech_3.6.0D_20110502_2.96_AR7WRD_psbl_firmware.img and it works a treat, thanks!
