It's 3 years old, so that's your "proceed with caution" note.

I did try the router database while I flashed a WRT54GS to disable IPv6.
Right now flashing it shouldn't be *required* The subsequent Cisco WRT54
series (after LinkSys acquired them) uses a newer Broadcom chipset,
invalidating this database.

Try cold-booting and running for 4hrs (at least) with both #1 and #2 here:
1. Test-run the WRT54G without any *incoming* and only *outgoing*
Wireless/Wired connections
2. Test-run the WRT54G with only *incoming* and _no_ *outgoing*
Wireless/wired connections

If it works in the above cases, you do not need the firmware upgrade.
Switch of SSID advertising. Change your SSID string to one you could easily

If you have other WiFi routers nearby including mobile hotspots, please
switch to channels 4..7 (1..3 are used commonly.)
