We need a new Wireless Access Point for our office.

Basically, we use MAC Address filtering currently to allow devices onto our company network. We have just reached 32 wireless devices (the maximum number of MAC addresses i can set on the AP) so will need to upgrade to something that allows more than 32.

Any recommendations? Budget upto £100 i would say. Only need to be an AP not a router.

Thanks,

Matt.

Why not switch to WPA instead?

Have a look at some of the custom firmware around, Tomato (IIRC) and DD-WRT for example.

How would that help his Mac filtering limit?
I assume the OP is running WPA as well as the mac filter....

Have a draytek that's pretty good, but I think it has a mac limit of about 40

I'm questioning the benefits that MAC address filtering offers when also running WPA.

I'm not sure how many AP's allow more than 32 devices. Typically the SoHo units don't. I expect because the channel becomes very crowded and the throughput drops off considerably.

If I was you I'd look at the following:

- Buy a second AP of the same model (or two new ones of the same model).
- Put one at each end of the office.
- Set up both AP's with the same SSID, WPA2-AES (assuming it's supported by your clients) but have them operating on different discrete channels one each on either Ch.1, Ch.6 or Ch.11).
- Ditch the MAC filtering.

Should reduce the load on a single AP yet allow "roaming" between the two if you move around the office.

Alternatively, you can use 2 separate SSIDs if you want to completely segregate.

I personally don't bother any more at home, if someone is sharp enough to break the WPA it won't be a huge issue to clone the mac addresses.

On a work network, I certainly would enable MAC filtering to stop employees "loaning" access to unauthorised machines.

Equally though, I'd argue that if employees are smart enough to show the WPA key in Windows / OS X they are smart enough to spoof the MAC on an unauthorised device...

On a PC, maybe. On a mobile phone or similar?

Fair point. :tumbup:

Right, and how are you going to do that then? By "accidentally" finding a valid MAC address?

Very easy. There are many free tools available that make it literally child's play to packet sniff the MAC address of a wireless client. It takes about 60 seconds to implement - I did it myself to prove to a "dangerous knowledge" neighbour that MAC filtering alone was no substitute for encryption. He got pissed when (with his prior approval) I cloned the address of his MacBook, looged into his Airport AP and applied encryption so he couldn't use it...!!!

Right, but you're an expert. I've got MAC filtering and SSID hidden. I wouldn't use encryption.

For the sake of 5 mins, I'd enable encryption (WPA2-AES if possible). It really is a no-brainer TBH.

I would. Just because your router won't give me an IP address because of the MAC filter doesn't mean I still can't capture all your unencrypted traffic for my various nefarious plans.

And I will sniff and clone a valid MAC that the router will allow in a couple minutes.

WPA on with a decent key is an absolute must unless you VPN everything.
Mac filtering is personal preference IMHO.

To be perfectly honest, given I'm on a 2 meg connection (sticks) with a monthly allowance of 110GB, fill your boots mate. Given the machines are rebooted nightly, if one of them couldn't get on due to an IP conflict, it would be less than 24 hours.

And if you can get a wi-fi signal through my 2' thick walls, you'll be licking the windows anyway! I can't get a connection in my bd kitchen, and thats next door to the bloody office where the router is.... :sigh:
