I have reconnected my first sky router as it tends to sync higher than the replacement they sent (obviously a difference between same routers but that aside).
I think i may have cracked it - thanks to posts from other on here.
(1) UPnP is broke - don't use it - it can cause your router to loose connection with your wireless clients.
(2) Speed selection - either select Auto 108 or b & g - if not the speeds on your wireless clients can take a nosedive every 20 mins or so. Note that you do not need 108 wireless adaptors on your client to select and use this setting. Just hope your neighbors don't use channel 6 and are too close. If you are having problems on channel 6 select b&g and another channel - this setting appears stable. An aside to this is if you are using wpa security it is best to leave transmission of your ssid on so others can see and avoid your channel stopping any interference - there are no security issues with this despite what others may say.
Best time to start the process below is after 8pm in the evening.
Leave the router to run for about 1 hour, do lots of speed tests and keep an eye on your Noise Margin. You may see your speed test results dropping by about as much as 1 MB over this period. If your NM is about 6.1 or 6.2 after a few speed tests - do a reboot from your control panel 192.168.0.1. After the reboot your sync speed will probably drop, but your actual download speed will increase and your NM will increase. This will give you a more stable connection and give you the highest download speeds possible. You may notice that when you run a speed test, your NM value will drop slightly but should go back up again.
Run again for about 1 hour and repeat if necessary.
Then leave your router on all the time if possible.
I now have 2 pc's connected wirelessly, with their firewalls ON (XP), the office network is all OK, no disconnects/freezes and no falling speeds.
The downside in doing this is that you will loose your gateway icon - so you will not readily see your connection speed, you will have to login to your router to get this.
If you play online games, you will need to configure the settings manually - or there are tools to do this for you at a price.
================================================== =====
How to do this if you are not sure and using your router for the first time
================================================== =====
(1) Just connect your router to the power and telephone socket and then either using your wireless connection (you will need to enter the passphrase given by sky) or your wired connection, put
http://192.168.0.1 into your browser url and press enter. You should see a login box appear, put admin and sky as the password(unless you have changed it). Your router screen should appear.
(2) Select the UPnP option at the bottom (by log off) and untick Turn UPnP On. Then click Apply
(3) Select Wireless Setting option (at the top) and select Mode Auto 108 Mbps. The click Apply at the bottom. If there are any other neigbors using channel 6 select b&g and a channel not obviously in use. If this still cuases peoblems try another channel (it would really help if people transmit their ssid so we can see what channels are being used!)
(4) Select Router Status (under Maintenance) and click show Statistics - this will show you your Noise Margin (NM) as discussed above.
(5)Do your 1 hour run exercising your connection as much as possible by doing lots of speed test and downloads
(6)After 1 hour, select the Diagnostics option (under Maintenance) and click Reboot. This will do a software reboot. You will loose your connection temporarily while it completes.
(7) Your done and should now have a stable connection. If not repeat from step (5)
