I'm only able to connect to my WRT54G v2.2 through wireless. The LAN- and WAN ports no longer function. I read here this may be caused by Alchemy firmware of which I indeed tried pre5.3. It failed to update my router so I continued with (wireless upgraded) linksys 3.03.6 and now 4.00.7. Can the ports be fixed or are they lost forever? Edit: I solved it doing a hard reset, but not as described on linksys.com.
