Anybody using one of these with wifi only.
Most are connected using an ethernet cable from router, but i would like to use through wifi if possible,just not sure how to set up.

Without knowing the exact model it is difficult to say what your specific options are.

The models on their website seem to be wired ethernet only and don't appear to have WiFi built in. Therefore your only option may be a wireless access point of some sort. For example

You would set it up initially by plugging a computer in it to link to your WiFi or, if your router supports it, WPS to do the set up automatically. Then plug the receiver into it and Robert is your Father's brother as they say

This is the model

That is one of the models I looked at. Trouble is there is not a lot of detail on their website and doesn't appear to be any manuals for download. There is a support forum link but you seem to have to register to do anything useful with it.

So I suspect you will need a WiFi access point connected via ethernet cable to the receiver such as the one I linked to above. I don't think there is an internal WiFi system in the receiver. If there were then it should appear in the setup menus in the section where you configure the network. If it did have built in WiFi there would have to be a way to select the WiFi network and enter the security password. A lack of this would indicate there is no built in WiFi.

You may find a TP link or "Firewire" maybe more beneficial to you if you have accessibility issues. You would suffer no loss of signal compared to possible deteriation using wifi aerials.

Thanks for the replys,think i will go with the tp link.
Which tp link would be best set up for zgemma,seems to be so many different models
