Review: Three’s wireless broadband thing-a-ma-gig

Sunday, December 16th, 2007

I’ve been using one of Three’s USB wireless dongles this week.
It’s an E220 modem; the same one that most of the other phone companies are using.

Conclution; it’s a nice piece of kit which is going to be very useful.
At 15 Pounds a month it’s comparable to a wired connection but without the hassle and day off work involved in getting a phone line connected.

Pros.
- It works out of box; it doesn’t take days to get it activated on the network.
- It seems to have pretty good coverage.
- It works on a Mac and the PDF explaining how to set it up was correct.
- It has a pretty light which changes colours.
- It works on the train! You just can’t put a value on that.

Technical Cons.
- Initial connections and DNS lookups are rubbish.
It takes several seconds for DNS queries to complete. New ssh connections take about 5 seconds to come up.
- It’s NATed. You don’t seem to get a real IP number and you can’t make inbound connections.
- It dropped ssh connections like they were going out of fashion. This was becoming a real issue until I realised why it was happening; you’re behind a really agressive NAT gateway which is timing out your connections as fast as it can. You just need to set an ssh keep alive.
- There seems to be a transparent http proxy involved. You can’t access an http svn repository from this connection. Solution; use an https repository.

Three just been silly Cons.
- The Mac instructions say use the Mac driver CD included but the Three stores don’t have any of them to give out.
- The driver download link on the Three website is broken.
You have to google for E220 drivers and then follow the Three instruction sheet.
- To get to your data usage page you need to register online using you SIM number (fine) and your Three phone number. Abit of a problem there as you haven’t got a phone number because you didn’t actually buy a phone. I’m not sure what the resolution to this is yet.

Extra for experts
The modem comes with a SIM card; does anyone know what happens if you put this card into a phone?
Can you make calls; can you use the phone as a bluetooth modem?

Stop press; we’ve actually written something that people want!

At Twickenham Rowing Club we’ve been tinkering with an online availablity system for the past couple of years. It helps our rowers and coaches co-ordinate the cat herding task of getting 10+ people in the same place, at the same time, four times a week.

It’s a fairly rough and ready system but it’s been working well for us and we havnn’t seen anything simular in the rowing world.

This week, we released our system for use by other clubs. Part of our motive for doing this, was to try and ensure the system’s future by:
a) expanding the number and diversity of users.
b) trying to make contact with people developing simular things elsewhere in the rowing community.

The response has well and truly exceeded my expectations.

I’d thought if we were really lucky we might get 5 clubs using it within the year.
After 3 days, we’ve had over 20 clubs sign up, with a good number of those actively using it.
We’ve also had one contact from a developer working on potentally complimentally system.
