Hi there, i am not sure if anyone of you is using this wireless router. I am using it, and try to enforce "Access Restriction" to some website, but i won't work.

Below is the screenshot for the Access Restriction:-
I want to block by MAC address: 08:00:37:0E:D B:21

please explain to me why it doesn't work :) 

thank you very much :wink:

access restrictions dont work for me either and i upgraded to the very latest firmware.

also be careful about 3rd party gpl'd firmware on the 54g. it turns out mine is a v5, which is incompatible with 3rd party firmware. before you go trying any of those firmwares, check that your router is not a v5!

Here are how you set access restriction on Linksys WRT54G.
First is Enter policy name. You must give this policy a name. Good naming convention is to name it after the software or persons computer you wish to control. Next is edit lists of pc, type in mac address of pc you want to restrict, Next is a choice, do you Allow or Deny access to the internet. Next you can block some URLs by url address. Some examples of url address are,, or Then you have Block by Keywords. Which is just certain words to look for and block the site if the site contains thoose words. Examples would be sex, xxx, or adult.Next you can block certain services I leave my NONE. Click Save settings

First: a policy must be enabled. (
I did one that enables access 24 hours a day (seem counter-intuitive but is necessary)

Second: You must select PCs to apply the policy to.
I used the IP Range setting so that everyone that connected would get the same policy.

Third: URLs must be entered as www.sitename.extension ie. etc. (http:// is assumed)

Keywords: Enter single words - no spaces or punctuation is allowed. (ie porn or nude etc.)

You need to hit applied PC's Edit List button and then to block it on any computer that could join your network put 1 to 254 in the IP Address Range

Well I don't know how to that, but I am surly anxious to know as to why you want to do that?? :??:

This is an easy one and it has to with your head. No wait, I do have the answer cause i just fixe the same issue. read on.

The way to write the policy is to understand that any period of time that is not explicitly denied/blocked by a policy, does have open access. Here is an example

I want to usage on my iPod to be limited to 5:45 am to 9:15 pm. Hence it is tempting to to define a policy that enables internet access between 5:45 am to 9:15 pm. The problem with defining such a policy is the undefined period i.e. 12 am to 5:45 and 9:15 pm to 12 pm are considered by default "open access".

The net result that that i have a policy that allows access for 24hour/day.

TO actually limit access to only between 5:45 am to 9;15 pm. I need to define two policies.
1. to block access from 12 am to 5:45 am
2. to block access from 9:15 pm to 12 am.


So in a nutshell, the access policies to work, you just need to understand the logic of the program. (very tiresome IMHO, they could have done it better,)

Access Restrictions dont't work. Tried with newest firmware aND several different ways. Booted the device etc... Sometimes seem to work but sometimes blocks the access even in allowed time.

The time selection control is very odd (hours from 1 to 12) and you just cannot express the time period what you want. Try to block access from say 22:00 - 07:00 and the software won't allow to to that.

Just wondering why they are doing newer firmwares but don't fix plain errors...
