Children by passing internet access rules

Question

I want to allow internet access to specific Mac addresses only.
My WRT54GL router, firmware V4.30.5 currently has rules to "deny" access to my children's PC's during certain times.
I use the PC's Mac addresses to do this.
However, they have learned how to clone their Mac addresses, hence bypass the block (last time I looked each of their PC's had acquired three licences from the router under different Mac addresses!).
If I set the router to only "allow" access at certain times (again using the Mac address), would using another Mac address just gain access anyway?
Would I also have to set up rules for my other PC's (wife's and mine) to allow us to have internet access.....currently, as I us blocking, there are no rules to allow or block these other PC's, they just connect anyway.

Answer 1

Exactly my point!  If the kids are getting too smart, they will do anything to get around your rules.  It will reach a point where you will need to put a lock on the circuit breaker panel and turn the power breaker off that leads to the router.  Then again, sneaky little b-tards may find an extnesion cord and power it while you are away anyhow!
You can't win unless you make it a house rule and stick to it hard.  I know more than you realize the consequences of doing / not doing this.  I had a child just like that, and when I finally cut him off completely because he was skipping homework
(failing in 2 classes)  and playing online all night instead, he decided to smash my computer in retaliation.  I really wish we had set those rules as unbreakable when they were younger before they decided to think they could pull one over on us as parents.
I'm not saying your kid will do something like that, but if you really care about what they are doing, you need to make rules NOW and make them follow them.  Otherwise you might as well just set them free now, because they are half way out the door already.
There is no technical answer to your delimia.  What I said about setting allow only on your computers MAC addresses will work until they learn what those addresses are and clone them too.
As for the functionality of the access restriction of linksys routers ... my opinion is not high right now.  I am fighting with tech support to fix a problem I have.  The ball is in my court right now.  They want me to do a factory reset and start over from there.  I just need at least a 2 hour window, because Murphy lives in my house.  I know it won't be sweet and simple to reconfigure everything again.
I'll let you know if the factory reset fixes my problems.  Better yet, upgrade your firmware to the latest, and then do the faactory reset and you'll be exactly where tech support has me at with fixing random bugs in the access restrictions arena.
