I had a DD-WRT router that was dropping a lot of packets. I got a lot of errors and that caused poor playback in Netflix and especially MLB.tv. It wasn’t a bandwidth issue. My wireless network connection was just too noisy.
Here’s how I fixed it. Continue reading Reduce DD-WRT packet errors
Insurance companies are starting to offer discounts if you plug one of their devices, often called a RightTrack or SnapShot, into your car’s ODB2 port.
One of my college buddies asked me about them when his insurance company offered his family a 5% discount to plug these into their cars, and then make them eligible for up to another 25%. Those are compelling numbers. So what are the potential drawbacks?

Since my advice on selling Tyco trains was well received, I thought I would give similar advice on selling Marx trains. Marx never got the respect that its competitors got, but its trains have built up a following over the years, and in the last decade as I’ve watched prices on competing trains slide, Marx has held its value.
Don’t expect to get rich selling off your Marx trains, but if you keep your expectations realistic, you’ll find an eager buyer, or ideally, at least two interested buyers so you’ll realize a good price at auction.

I got an inquiry last week about selling Tyco trains. As a child of the 70s and 80s, I certainly remember Tyco, and in recent years Tyco has gained a bit of a following.
If you’re looking to sell some Tyco gear, you certainly can do it, but you have to keep your expectations realistic. You’ll probably be able to sell it, but don’t expect to get rich off it.

A Slashdot story last week discussed how 90% of all SSL VPNs use weak, obsolete encryption. And one comment said, “So? A weak VPN is better than no VPN.”

I had a Java app pointing at a Websense (now known as Forcepoint) proxy server. The proxy server wasn’t working, and the app was giving me a 407 error.
We had Websense set to require NTLM authorization, but it turns out Java won’t do NTLM, so the Java traffic wasn’t even showing up in the monitor.
My workaround was to have users open a browser, then go to any web page immediately before opening the app. By letting the browser authenticate for it, the Java app worked thanks to Websense having the credentials cached.
If you want, you can launch the applet with a batch file that uses IEcapt to hit any web page, then starts the applet.
The other question that came out of my recommended DD-WRT settings was why not filter MAC addresses.
The reason is because your MAC addresses are broadcast as part of the network traffic, and it’s unencrypted, so your MAC addresses aren’t any secret at all. It doesn’t really do any harm, but it doesn’t do any good either.

I got a couple of questions about my recommended DD-WRT settings, but I’m going to start with the question about why not to hide the SSID. It actually turns out that hiding your SSID is bad for you, and makes your security worse. I’ll explain.

If you need an inexpensive DD-WRT compatible router, TP-Link is probably your best choice. But there are some big differences when you compare the TL-WR840n vs the TL-WR841n.
I’ve been running the TL-WR841n for more than two years, so I’m familiar with it. I’ve considered supplementing it with a secondary router, and the TL-WR840n was one I looked at.
