You need to adjust your tinfoil hat a little tighter to understand why you need to be unique and to broadcast your SSID at home at the same time. I think the keyword is butterfly, or is it rainbow hash tables? I forget which, but anyone can download the hash for any of a million common passwords (this was years ago, so it's probably ten or twenty million by now) for all the common SSIDs.

I generally change the web port from 80, and I change the SSH port from, I think, 443, to something else, to make robo logins a bit more difficult (it won't help against a determined hacker, of course, nor a determined robot, but, it's easy enough to do, and, for me, it stopped a million login attempts that were hammering my router's cpu rejecting them).

I login all the time to my rooftop router, and to my neighbor's rooftop routers (since we're all on the same subnet), just to see what's going on. It's how I found out that robots were hammering my system, and, how they stopped while still hammering my neighbor's systems, when I switched the ports. $ ssh -p 4545 -l adm1n 192.168.2.1 BusyBox v1.11.2 (2014-10-01 16:45:24 EEST) built-in shell (ash) Enter 'help' for a list of built-in commands. XM.v5.5.10# tail /var/log/messages In fact, you can see good stuff for debugging, for example, you can see what DHCP is used and what IP range is on the LAN, etc. $ cat /etc/dnsmasq.conf You can even log into your neighbor's rooftop router and see what domains they visit. $ cat /proc/net/nf_conntrack It's not wireshark nor netstumbler, but, it's a decent log of everywhere the router has been (less cryptic than wireshark output for example).

There's a setting to enable or disable hardware reset on *every* rooftop radio that I have seen. Here's a picture of one screen of my rooftop router's configuration: http://i.imgur.com/ow0WyR8.jpg Of course, these WiFi radios also have sliders for signal strength, distance, channel width, dynamic dns, telnet servers, web servers, ping watchdog, snmp agent, ssh server, ntp client, system log, etc. Point is that these routers have more features than your average mom-and- pop router, as Jeff well knows.

Nice hardware. >Point is that these routers have more features than your average mom-and- >pop router, as Jeff well knows. Yep. Features and functions get added faster than bugs get fixed. I really hate security discussions. They never end, never reach a consensus, there's always one more security hole, and even those routers that are certified and blessed by an expensive certification organization, are problematic. Anyway, permit me to point out the giant gaping monstrous security hole, that most users can't see or just ignore. It's the WPA-PSK shared key. Every computah, tabloid, smartphone, xbox, etc that connects to a single secured router uses the same pass phrase. Considerable effort has gone into making this pass phrase difficult to sniff and recover. Yet, all it takes is one insecure client radio, and the pass phrase or usable hash code can be recovered. Here's a good example: <http://www.nirsoft.net/utils/wireless_key.html> If you have an Android tablet that's been rooted, there are several utilities that will display the saved pass phrases. I use this one: <https://play.google.com/store/apps/details?id=com.wifipass.recovery> Steal my ancient Droid X2 and you can see *ALL* my wireless pass phrases. Note that it doesn't matter if you're using WEP, WPA-TKIP, or WPA2-AES encryption. The password is there in plain sight. I assume there's something similar for jail broken Apple products. So whatcha gonna do? Well, big business uses a WPA2-Enterprise-AES with 802.1x and EAP authentication. You could too, except that there is only one commodity grade wireless router that includes the necessary features (ZyXEL G-2000 Plus) and it's rather limited with only 5 logins. You'll either need to subscribe to a service, or build your own RADIUS server: <http://freeradius.org> <http://wiki.freeradius.org/guide/WPA-HOWTO> <http://wiki.freeradius.org/protocol/EAP> <https://play.google.com/store/apps/details?id=com.larscom.freeradiusandroid> So, how duz it work? Very roughly, each user gets a login and password from the RADIUS server when connecting. If they successfully login, the RADIUS server delivered a one time WPA2-AES key to the clients wireless device, which is only good the current session. Disconnect, and you get a new key. I won't go into the EAP authentication part (mostly because I barely understand how it works). There are also lots of variations, such as no user/password on login, which is the easy way to do encrypted coffee shop systems. The RADIUS server does not need to be inside or next to your wireless router. It can be anywhere on the internet. For example, the University of Calif runs one that covers all their facilities. A user can login literally anywhere on the UC system and get authenticated for the entire system. I run my RADIUS server in my office and in a server farm for several of my customers systems. There are also services that will do it for you. Here's an example of an online service that puts the RADIUS server in the "cloud": <http://cloudessa.com> Before the inevitable demise of wireless as we know it, perhaps the router manufacturers will cease advertising astronomical wireless speeds and do something about the pre-shared key security problem? Naw, it will never happen. Security doesn't sell routers, while big number do. -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

Yep. I forgot about that. <https://www.dd-wrt.com/demo/FreeRadius.asp> (click "enable").

The best router I can find (with high speed ethernet & n/ab/), 5/2.4MHz 3. I'll try to talk Comcast out of the $50 service call also (as advised here).

That happened a few weeks ago at one customers, where >mice had chewed through the coax trying to get into the house. Same experience here. I always hear the stories about them blaming a customer-owned modem, but I've never experienced it.

Yep, like I said in the part you snipped out: Comcast controls the modem configuration, but you can still access the modem's built-in management web page (http://192.168.100.1/) to look at how it is configured, check the logs, reset it, and so on. -- E-mail sent to this address may be devoured by my ravenous SPAM filter. I often ignore posts from Google. Use a real news client instead. JR

(very different from docsis config which is done whenever modem connects to the coax network). So it is possible that Comcast accepts "off the shelf" modems because its CMTS detect wrong firmware and and automatically push their firmware onto modem. (This is different from canadian carriers who do not accept modems with wrong firware, and only do "mass" firware upgrades to fix known bugs in modems).

Interesting policy. > In general, do they let you have root privileges on the modem if > you buy it yourself? When the modem powers up, it asks the coax side for its settings. The CMTS then provisions the modem with a whole bunch of stuff, from encryption keys, your customer profile (speeds, number of IPs allowed etc), and modem specific stuff (such as disabling access to the modem from the LAN which is something canadian carriers do). The modem manufacturers provide cable carriers who a whole bunch of options on how to restrict the modem. (similar to handset manufactyirers who give carriers ability to change home menu, disable functions, add their crapware etc).
