2.4Ghz Wi-Fi Interference

Vu+ Newbie
I have an Ultimo that's networked via the VU+ dongle. I've always suffered from occasional glitching and freezing. Although recently it's become intolerable. I've been aware of the Wi-Fi interference on the 2.4Ghz frequency, which is why I purchased a dual band router. Although the Netgear 5Ghz dongle (WNDA3100v2) has a Broadcom chip and apparently it isn't supported by VU+ so I've had to sit it out.

I've Spectrum scanned our neighbourhood to ensure none of my neighbours are on the same channel, but I obviously rely on people broadcasting their SSID for an accurate assessment. Also, new routers scan for conflicting channels and move the owner's onto a vacant channel should their be a conflict, but it might be enough to cause interference as the router dynamically reassigns channels.

Apparently microwaves, baby monitors, cordless phones and other wireless devices share the same 2.4Ghz frequency, so it's possible that that it's what's causing my glitching. I believe people who stream Netfix over Wi-Fi also suffer from the same glitching/freezing.

I've checked remote pings which are 35ms, SNR is 88 and AGC is 79. The E parameter has been known to fluctuate wildly over Wi-Fi, hitting 2.6 and as low as 0.50'ish, but is in the region of 0.100 and 0.200 hardwired. I would of course hardwire the RJ45 if possible, or use homeplugs, but my setup doesn't allow me to do it.

Will support for 5Ghz dongles be forthcomng on BH images? Will the Broadcom chip be supported in the near future? Because I need to get off the 2.4Ghz band because it's now saturated!

Cheers Ian

Actually your dual band dongle is not yet supported on Linux :(
 
Yeah, I just hope we will see better 5Ghz Wi-Fi dongle support in the near future. Using the RJ45 has proven to resolve 99.9% of all glitching and freezing. I'm confident the 5Ghz frequency will prove itself to be interference free, albeit for now. For now my Netgear WNDA3100v2 will be mothballed in the draw until drivers are released :/

Obviously, people's experience with 2.4Ghz interference will be dependent on where they live. If they live in a remote area it will be relatively intereference free - depending on what other wireless devices they have. But if you're like me and in a built up area, then you're at the mercy of who uses what around you.

You can purchase USB analysis spectrum scanners like the WifiSpy, although they're very expensive, and they won't resolve the interference if you're not the owner of the device emitting it, but will only pinpoint the location of the source.
