      Is this an Acceptable Signal/Noise Ratio - Signal -90, Noise -75 (D-link Router)

      Hi, Got the results below on Wi-Fi Diagnostics, Tested it as my old Imac Can't get an airport signal when the router is downstairs.
      Have recently received new 'splitters' from Sky as the Sky BB guy, said the Noise was massive and needed to do something about it.

      The stats can be obtained in the same way as the Netgear 934 and Sagem 2504, the GUI is identical. Without the attenuation and noise margin, there is not much we can say. For stats it does not matter whether you use wireless or ethernet, although there can be a big difference for speedtests.

      By posting the stats. Click the 'Show statistics' button at the bottom the the Status page. The router Status, which you have posted, shows what you have, not what you could have.

      No It's very weak I suspect most devices will have trouble connecting to the network with that signal strength.

      Generally speaking you'd want -67 or better for mobile devices (Ipads.etc), for laptops.etc it will depends on the network adapter some of them will still work close to -80 but beyond that it's likely to be very hit and miss.

      The higher the number the weaker the signal as it's a negative value.
