If you insist to use the TG585, first make sure it will accept new devices (see the wireless settings of the TG585). Next, don't use automatic settings on the CPE, but use fixed b/g mode, channel width 20 MHz, no encryption. If that works, set the CPE's encryption parameters according to what the TG585 supports. Also make sure the TG585 is in range of the CPE's 65° antenna beamwidth. Expect no more than 54 Mbps wireless speed and 20 to 25 Mbps data speed with such an old device as the TG585.
