Is there a limit to the number of MAC Address that I can allow access to? My current router has a limit of 32 and I wasn't sure if there was a limit on the DD-WRT firmware. I am trying to set up a WiFi at my local union. Thanks in advance.

remember the nvram limitations of most routers (32k, or 60k)

each mac filter entry will consume 18 bytes..

I'm using a Cisco - Linksys WRT54GL with DD-WRT - DD-WRT v24-sp1 (07/27/08) std

I'm blocking WiFi access and only allowing the MACs in the MAC Address Filter List to have WiFi access. There is room for 128 entries on the page, however, if I put in anything past 32 then no one gets WiFi access.

How can I fix this?

I saved the configuration of the router and upgraded it to:

DD-WRT v24-sp2 (10/10/09) std
(SVN revision 13064)

I didn't realize that it was a newer build than what I had until I posted the last message. I had installed the firmware this year so I assumed when I looked for a firmware upgrade that I had anything the was put out in 2010.

It seems to be working now.

Before the Firmware Upgrade, I was able to setup the 33rd MAC and it initially worked but at some point all WiFi stopped and would only work when I would turn the MAC filtering off.

The firmware upgrade was pretty smooth.

The firmware that upgraded to is listed on the web as:


Standard Generic dd-wrt.v24_std_generic.bin 2009-10-10 3,54 MB

which is:

DD-WRT v24-sp2 (10/10/09) std
(SVN revision 13064)

But you don't know that until you've installed in your router and can see it at the top right corner.

I think this makes it harder to know when you need to upgrade.

You have gone from worse to bad. You need to read the peacock announcement. Those are both bad builds and flashing your old config could have bricked your router. And before you say that these builds are the ones in the router database....I know. They are still bad. Read the Broadcom forum announcements.

I've looked to for the posts that you sent me a print screen of and I cannot find them.

I rebooted the router just to make sure that everything comes up as expected and it seems fine.

What exactly is supposed to be messed up in this build?

One of the posts you had circled had a subject that the user had lost their web interface. If they were talking about the router's own web interface then that hasn't happened yet.

If this build is bad and the previous one we were on is only a little better then what build should I be on?

Broadcom forum. Top of the page. That screenshot is part of my signature. I didn't actually send it to you.

You are in the "General" Forum.

Ok, I see that now.

From what I can see everything's working fine with the router right now.

I'll look take a look and see what I can find in the forum.
