Recent Thoughts About The Edge of My Network

monowall-pfsense-alix-kitIn recent weeks I’ve been accumulating some thoughts about the edge of networks, and the edge of my home office network in particular.

This all started last month where there was an Ars Technica article describing how someone found a backdoor that allowed an evil-doer to gain admin access to a common consumer combination DSL Modem/router/Wifi AP. The author initially proved the exploit by hacking his Linksys WAG200G wireless gateway.

The article describes how he published the script used to run the exploit. That allowed others to try the exploit against various makes/models of consumer hardware. It thus came to light that the same trick works against various products from Linksys and Netgear, amongst others.

A Tale Of Wonky Wifi Part 4: A Doubleheader Featuring 802.11B/G vs N, And WLAN vs Mesh

When last we left this story our protagonist had returned the Cisco AP to BUY.COM leaving le maison du Graves without functional wifi for about two weeks. Fortunately I was out of town a lot during that period so it wasn’t much of an inconvenience. If anything it gave me some time to evaluate my options regarding replacement gear.

I’ve noted that whereas I had a lot of problems with 802.11n type wifi APs I’d previously had far fewer issues with 802.11g type hardware. Very recently I was reminded by someone who should know that 802.11a/b/g is more mature hardware than 802.11n. This certainly rings true as my very old Linksys WAP-54G ran for literally years with no problems at all.

How I long for the Linksys of old.

A Tale Of Wonky Wifi Part 3: Wifi Access Point vs Router

There are myriad inexpensive consumer routers available that include wifi functionality, but far fewer freestanding wifi access points (AP.) I surmise that this is because every broadband connected home needs a router and wants a wifi AP, so a converged device is the most affordable approach to this marketplace. Yet in many ways it’s less than ideal.

The fact that your router and wifi access point are in one device makes that device a major possible single point of failure. It dies and your entire network goes down. While merely inconvenient for the kids coming home after school to play World Of Warcraft, it’s a whole different kind of failure if you’re a full-time home office worker who relies on internet access to be effective in your job.

A Tale Of Wonky Wifi Part 2: Some History & Seeking Advice

This is part 2 in the continuing saga of my fight with replacing a dead Netgear WNR-2000 that had served a my wifi AP.  Please recall that I just RMA’d the Cisco WAP4410N that was to be its replacement.

Firstly, I think that I was a very early adopter of both residential broadband and wifi. Linksys was the obvious leader in devices for this market. I bought a Linksys WAP-11 when they were brand new and fairly pricey. I wired it into my trusty Linksys BEFSR-41 4-port wired router. That device was fed by a Time-Warner Road Runner cable modem back in 1998.
