Wow thats bad

I originally intended to do a piece for the blog every couple of weeks or so but as I have the latest test data I may as well put it up a bit early.

So I got to thinking, I still have my original 2Mbps ADSL circuits, which both have wireless routers. Perhaps one of these will have a better wireless AP I could use instead of the BT Home Hub. I have the routers all connected to a shared switch so that I can arrive on any wireless AP but then route to the Internet via the new 40Mbps circuit. This is done by manually setting IP credentials on the laptop, in particular the default gateway and DNS IP addresses. So by changing the IP address for the default gateway I can push my Internet traffic via whichever DSL or fiber circuit I like independent of which wireless network I’m connecting to.  So should just be a case of repeat the original tests with the laptops connected to the AP I want to check, but default gateway always set to the 40Mbps link.

I have a 2Mbps ADSL from Sky (its free and good so why wouldn’t you) and a 8Mbps BT Internet ADSL which can just about manage 1.5Mbps - on a good day (distance issues). I’m intending to cancel the BT one once I’m happy the 40Mbps Infinity is stable and reliable. I’ll keep the Sky as its practically zero cost, reliable and will make a good backup.

I’ve already changed out the DSL router on the BT connection from the old style home hub to a Netgear DG834PN RangeMax that I bought in the hope it would improve the DSL connection speed – it didn’t. As it’s a newer router and has a better firewall (imo) I kept the Netgear and it’s been giving good service for the last 3 years or so. The Sky router is the standard one they shipped with the service – which I think is a rebadged Netgear as well.

So I started testing the Sky DSL router wireless with high hopes of improving my wireless performance – not a chance. As soon as I moved out of the room the performance fell off a cliff – a very big cliff at that. In several instance connection was repeatedly lost during testing, preventing any result of the speed test.  

The following table shows the results for the Sky routers wireless.

OK so now I’m thinking perhaps my Sky router is seriously past its best so moved on to the Netgear DG834PN connected to my BT ADSL. This was definitely better than the Sky router as I would have anticipated,  but roughly half as good as the Home Hub and still some dead spots. As with the Sky router, wireless performance plummeted as soon as you moved outside of the same room.

This is what the blurb said that persuaded me to buy the Netgear:

 “With RangeMax dynamic connectivity there is no need to spend extra money on range extenders, repeaters and external antennas. There is also no need to throw away your older wireless devices; the DG834PN wireless modem router is compatible with 802.11b, 802.11g and SuperG™ products and will boost their range and speed. Coverage is maximised when the DG834PN is used in conjunction with NETGEAR’s RangeMax™ PC cards and adapters.”

Well it’s definitely doing something better than the Sky router but its performance was still down compared to the Home Hub.

In summary, here’s the Home Hub results from the last post and the Sky results in a single table for comparison.

I’d include the Netgear as well but the table is too crowded, you get the idea anyway.

Conclusion

• My Sky routers wireless performance is plain awful compared to the Home Hub, its just worlds apart.
• The Netgear with “RangeMax” technology was able to give better speeds but struggled with reach almost identically to the Sky Router.
• All wireless routers are not created equal and you cant use ABG/N specification as a measure of how good they are. Spending cash on a router doesn’t make it better than a free one.
• The technique for using different wireless vs gateways works well and will allow me to swap between Sky and Infinity with a software switch. Also allows for different APs to be introduced if I can find one with better performance than the standard Infinity Home Hub.

Next

Support call to Sky to see if the performance I’m seeing is expected behavior and if they can offer anything better. If they do, I will test it and share the results.
