Troubleshooting: isolating latency issues

[Cavery1962]

I know I'm not answering your question directly, but:  If your router does not have an ethernet port, I think you need a new one which does. If the problem is that your router is not in the same room as your computer, a 100 foot cable is available on Amazon. Also available are adapters, e.g., ethernet to USB, to connect a laptop with no ethernet port. -- Cyril Penn

Hi,
     Thanks for the response.  Unfortunately it isn’t practical to run a cable from the music room to the router which is in the lounge, without a lot of inconvenience to the rest of the household.  I might be able to do something temporarily to test it out. Currently we have a wireless repeater which improves the wireless signal upstairs.  Are we basically saying that wireless is just not workable ?  Do you know what the minimum upload speed should be ?
