I'm on Mountain View's free city-wide network!

My worries about a large tree bewteen my apartment and the nearest meshed wireless router turned out be a complete non-issue.

I picked up a PepLink wireless modem and placed it on my window sill facing the meshed wireless router. From the sill it has near 100% signal strength.

To the wireless modem I've connected my household variety wireless router. The route trace to the gateway looks like this (you may want to refer to my previous blog entry for pictures):
 1  192.168.1.1    0.908 ms    (household wireless router in my apartment)
2 192.168.20.1 2.804 ms (wireless modem on my window sill)
3 64.9.230.10 4.021 ms (meshed wireless router outside my apartment window)
4 64.9.228.124 12.852 ms (meshed wireless router nearer the gateway)
5 8.6.48.5 17.463 ms (gateway)
The speed is decent. It's about 500 kilobit both upstream and downstream. That's faster than DSL but about one-quarter the speed of cable. We'll see how the speed fares as more people consume the network's bandwidth.

Of course, the best part is it's free. Whereas cable costs $50 per month. My plan is to trial the free network for a month or so, and if I'm happy with it then I'll cancel my cable connection.

Google has a FAQ up. The FAQ has a map of all the meshed wireless routers. It's far, far more extensive than I thought it would be.

This is how the internet should be...FREE!!! Comcast will probably offer a huge discount to the Mt. View residents who call in to cancel their service

An update a few hours later...

For those hoping the Mountain View wireless network will allow you to SSH/telnet into the computers on your network, or better yet allow your computers to host your web site, I have good news and bad news.

The good news is the meshed wireless routers hand out a routable network address. This would, in theory, allow you to set port forwarding for the devices within your home network, forwarding the correct ports to the correct computers (eg. port 80 HTTP to your web server).

In fact, from a computer external to Mountain View's network, I can traceroute my wireless modem's IP address all the way down to the meshed wireless router just on the outside of my apartment.

The bad news is, that meshed wireless router chooses to NOT forward the packet on to my wireless modem.

There is no technical reason why it can't. Probably, Google has purposefully disabled the router from doing so.

I can certainly understand why: people with their own web sites tend to hog way too much bandwidth and slow down the network for everyone.

However, I'm betting that at some point Google will offer a premium service. The premium service, I bet, will include a static IP address for your wireless modem, and a flip of the switch on the meshed wireless router that'll allow it to pass packets through to your wireless modem.

For a fee, of course.
