Linksys WRT54G v4 Router EWRT Firmware 0.4.3

Changelog:

- Three major functional fix-ups for NoCatSplash: 
The peer data can now be synced to a file with each auth/unauth, and leases re-initialized across server restarts or reboot. Simply define LeaseFile in your nocat.conf (set NC_LeaseFile in nvram on ewrt)
The redirect didn't wait for the firewall scripts to finish, often resulting in a user getting the splash page a second time.
The DHCP server would occasionally recycle "pulled" leases too quickly, and a user would be trapped in a loop on their new IP, since it was still in the peer database with the old MAC. They automatically replace the old lease now. 
- A few changes to generalize the model dependencies and config process in expectation of major changes and adding more supported hardware, coming in ewrt-0.5.
- Fixed the ipkg and ipkgtmp scripts to do the right things in the right places. I added an ipkg.conf which fetches packages from our website by default, but this can be overridden by setting IPKG_CONF_DIR.
NOTE: ewrt-0.4 will only run ipkg-ed kernel modules for 2.4.20, or binaries linked statically, or to the installed uClibc-0.9.19 libs.
- A bunch of new logging to syslog in the init process and callbacks for udhcpc events; I moved some of this stuff off of the serial console to make that easier to use as well.
- A new nvram variable: ip_conntrack_max, which will set the corresponding /proc entry (if >1024) at boot to raise the limit on the number of NAT-tracked connections. This is useful if you have a lot of users and start getting messages in the syslog saying the limit has been reached.

About Router Firmware:

Before you consider downloading this firmware, go to the system information page of the router and make sure that the currently installed version isn’t either newer or matching this release.

Due to the large variety of router models and different methods for upgrading the device, it is highly recommended that you read and, above all, understand the installation steps before you apply the new firmware, even if you are a power user.

In theory, these steps shouldn’t be much of a hassle for anyone, because manufacturers try to make them as easy as possible, even if they don’t always succeed. Basically, you must upload the new firmware to the router through its administration page and allow it to upgrade.

If you install a new version, you can expect increased security levels, different vulnerability issues to be resolved, improved overall performance and transfer speeds, enhanced compatibility with other devices, added support for newly developed technologies, as well as several other changes.

If you’re looking for certain safety measures, remember that it would be best if you perform the upload using an Ethernet cable rather than a wireless connection, which can be interrupted easily. Also, make sure you don’t power off the router or use its buttons during the installation, if you wish avoid any malfunctions.

If this firmware meets your current needs, get the desired version and apply it to your router unit; if not, check with our website as often as possible so that you don’t miss the update that will improve your device.
