Linksys WRT54G DHCP problem with Mac

Recently upgraded the firmware of my Linksys wireless router (WRT54G) to v1.00.10 and cost me 2 days in finding out what the hack was happening.

Once upgrade, only my Mac no longer be able to connect to anything online becuase it wasn’t assigned no IP address. My wife’s IBM notebook is working ok.
Later I found out that its the firmware causing all these trouble from Linksys forum. So until there anything fix out there. You would rather stick to v1.00.9 instead.

Download v1.00.9 firmware is available from their FTP.

Possible Broadband Connection Problem with Mac OS X

This problem only happens to me when I’m using the ISP with EnterNet 300 and it’s definitely a “mtu” related problem and more or less due to the tuning of ISP itself. You won’t notice it until you are downloading email or web page or anything which never get through.

If you happen to have problem getting through a EnterNet 300 broadband connection, you may try this “sudo ifconfig ppp0 mtu 1400” in Terminal where ppp0 is the connection to your broadband modem.

The last number can be anything lower than the default 1500. You can check the available connection by issue “ifconfig -a” in Terminal.
