Poor 5Ghz wifi performance?

[PsyberEMT]

Anyone else use a 5Ghz wifi network and notice slow performance with the Dinc4G? I have a dual band router, with one network on 2.4Ghz, 20Mhz of bandwidth, lots of interference since I live in an apartment complex of mostly younger people. Everyone has a 2.4Ghz network, most of them are bandwidth hogs and are using 2 bonded channels, so the 2.4 Ghz performance isn't great around here. The Dinc4G gets a solid 65mbps connection on the 2.4Ghz side anywhere in the apartment.

My 5Ghz network is 2 bonded channels, 40mhz, the only detectable network on 5Ghz high anywhere in the complex. My PCs average between 240-300 mpbs on this network anywhere in the building. The Dinc4G barely breaks 20mpbs connection and has latency issues, constant wifi drops, etc.

I'm running a Netgear WNDR3400 dual band router with DD-WRT.

Isolated hardware issue or is this a known problem with these phones?

I haven't noticed any issues with mine but then I haven't put actual numbers to it. I haven't had drop outs or anything like that though.

I can say that I've been experiencing similar issues with a Linksys WRT 610N v1 device, which is configured similar to yours. I'm also utilizing the 5Ghz band for the same reasons. While I haven't measured speed, my Dinc4 is constantly dropping connectivity, despite excellent signal strength. Moving to the 2.4Ghz channels seemed to make it worse.

I have the Netgear WNDR3700. I tried using 5ghz and the speed was the same but with much less range. I use WiFi analyzer on my phone to compare signals and the 2.4ghz signal is always stronger than the 5ghz. If I'm out in the yard I pick up the 2.4ghz but lose the 5ghz altogether. From what I read this is normal, 5ghz has less range than 2.4ghz?

For what it's worth, I use 5GHz for the same reasons with a Netgear N600. I'm usually seeing connection speeds between 52 and 72Mbps and no connection drops. This is being used in my condo & on the balcony. Maybe 1800 sq ft. My tablet, which runs on the 2.4 has frequent connection drops.

Canpitt27 - Yes, 2.4 will typically yield better range due to the signal propagation of 2.4Ghz vs 5Ghz. A radio signal transmitted at the same power from the same gain antenna at 2.4Ghz will typically propagate farther and penetrate structures better than an equivalent 5Ghz signal. 5Ghz is beneficial for users like me in an area with congested 2.4Ghz bands as a means of eliminating interference from nearby wifi networks running on the same frequencies. Multiple access points utilizing the same channel interfere with one another and can lead to packet loss, poor signal to noise ratios, etc. 2.4Ghz is also occupied by bluetooth, cordless phones, and can suffer interference from poorly shielded microwave ovens.

5Ghz is a newer standard in the US, so there aren't as many users on it (yet lol). Of course all of this is dependent upon the quality of the radio equipment in question. I should be seeing results similar to Jafmf95's, where the 5Ghz signal is of a higher quality than the 2.4Ghz signal, but that isn't the case sadly . Neither band is particularly impressive on the Dinc4G, though I do experience more drops on 5Ghz than I do on 2.4Ghz, which makes no logical sense as the 5Ghz signal is of a much higher quality throughout my building than the 2.4Ghz.

I have very frequent drops on 5ghz. And none on 2.4. From what you explained that makes sense. I definitely have leas range with 5ghz. I lose it if I go upstairs in my house.
Thank you for the very good explanation. I understand much better now.

Glad I could help! I'm usually the one on the receiving end of help on XDA as I'm far from an Android / Linux guru heh.
