MAC address filtering in DD-WRT

MAC address filtering in DD-WRT

I don’t recommend MAC address filtering–it stands for Media Access Control and has nothing to do with Apple computers–as a security measure. It’s too easy to bypass it. But if you want or need to do MAC address filtering in DD-WRT it’s easy to do.

And admittedly, even though MAC filtering won’t help your security, DD-WRT’s implementation of it lets you do some neat tricks that an off-the-shelf router can’t do–like forcing a device to use 5 GHz even if it wants to use 2.4 GHz.

Digiland tablet review

Digiland tablet review

The Digiland DL718M tablet is an inexpensive (sub-$40) tablet sold at consumer electronics stores like Best Buy. Make no mistake, a Digiland tablet is a basic tablet for basic needs. But given reasonable expectations you can buy one of these and be happy with it.

This isn’t a new market by any stretch. But it seems like tablets in this price range are usually Black Friday specials, or only available on online marketplaces far abroad. The Digiland DL718M is one you can get today if you want.

How to find inexpensive routers to run DD-WRT

How to find inexpensive routers to run DD-WRT

I’ve been using and recommending DD-WRT for years, but it’s getting harder to find inexpensive routers to run DD-WRT. Many inexpensive routers now use non-Broadcom chipsets that DD-WRT and other third-party firmware don’t support well, or at all.

But there’s still a way to get inexpensive, compatible routers that isn’t likely to change any time soon.

Build the best, most secure wifi in your neighborhood

My neighbor asked me for advice on setting up wi-fi in his new house. I realized it’s been a while since I’ve written about wi-fi, and it’s never been cheaper or easier to blanket your house and yard with a good signal.

Blanketing your house and yard while remaining secure, though, is still important.

What to look for in a wireless access point

A good way to eliminate dead zones in your house where wifi doesn’t work is to add one or two wireless access points to your setup.

Access points, thankfully, are no longer stupid expensive–they used to cost twice as much as a router in spite of being nothing more than a cut-down router–but almost every access point I’ve looked at has one or more compromises built in. That said, if you want something you can plug in and configure by filling out three or four things, you might be willing to live with those compromises.

Initial upgrade reports on the HP Stream and Pavilion Mini

Earlier this year at CES, HP introduced its HP Stream Mini ($180) and Pavilion Mini ($320 and $450) mini-desktops. They’re small, inexpensive, and in the case of the Stream, silent. They turn out to be surprisingly upgradeable as well. Ars Technica has details and benchmarks, but of course I have my own priorities based on their discoveries.

If you’ve been delaying upgrading your network, keep delaying

If you’ve been procrastinating about deploying 450-megabit (802.11n) wi-fi to your house, I have a reason for you to procrastinate a while longer: Gigabit wireless (802.11ac).

It’s only about twice as fast as its predecessor, which pales next to the 8x improvement 802.11n provided over 802.11g, but if you’re wanting to stream HD media through your house, you’ll notice the difference.

Attack of the $99 Droid-Pads

A 7-inch, underpowered Android tablet that may or may not be available at your corner Walgreen Drug Store is made some big waves today.  It’s underpowered, but it’s supposedly on sale for 99 bucks. Regular retail price is $129.

Yes, for 99 bucks, it’s a toy. But it could be a fun toy. Read more

How to secure your wi-fi router

It’s not enough to know what to look for in a router. I wanted to get some solid advice on wi-fi network security. Who better to give that advice than someone who built an airplane that hacks wi-fi? So I talked to WhiteQueen at http://rabbit-hole.org, the co-builder of a wi-fi hacking airplane that made waves at Defcon.

Hacker stereotypes aside, WhiteQueen was very forthcoming. He’s a white hat, and I found him eager to share what he knows.
