andrew027: After posting my more than acceptable speed test results last night, this morning it's still pretty bad.
So I went around the house and made sure every wifi device in the house was off, connected my PC via cable to one of the Ethernet ports on the Telecom-supplied TG589vn v2 router (which was the "recommended" method for doing the speed test), and here is the result:
Still more than happy with that.
Next, I disconnected the cable and re-ran the test connecting to the router via wifi, and here is that result:
As you can see, it's sh!te. The behaviour of my wife and daughter's iPads and my Android phone suggests to me we're all getting this kind of performance wirelessly. So the problem is not with the Telecom network, or my house wiring, it has to be the wifi connection, right?
When I look at the router, the Power and Broadband LEDs are green - solid on. The Internet LED is green - blinking irregularly, which I take to mean sending and/or receiving data. The Wireless LED is also green - blinking. The manual says this means "Wireless activity, WPA2-PSK or WPA-PSK encryption", but I don't think it's blinking in time with any connected activity. It's just blinking constantly, really fast (approx. twice a second) all the time, even when all the wireless devices in the house have wifi turned off. So I'm wondering if this indicates some kind of unusual activity but the router itself that is interfering with the connections to wireless devices in the house, hence the apparent poor performance.
I found the wifi performance of the TG589 is not that good. I end up using it in bridge mode and than use a TP-link router (with no ADSL or VDSL support, just a router) to do the PPPoE authenication and wifi as it provides better wifi coverage.
