Hello!

I got my new i9505 two weeks ago, and I'm having issues with Wifi connection.

I have both Galaxy S III and S4. Next to the router (100/10 Mbps HFC connection), my Galaxy SIII reaches 27/10 Mbps, and my Galaxy S4 reaches 30/10 Mbps. That speeds fluctuate (15-40 Mb) but I can say that's a good connection in the phones.

But when I go away a few meters from the router (5-10 meters), the S4 speed drops to 3-0.01 Mb. Yes, 0.01 Mb, when Galaxy SIII drops only 0-5 Mbps less. Curiously, upload speed is usually kept on both phones.

Here are some results from Speedtest.net, left Galaxy SIII right Galaxy S4:

(Sorry, I can't post outside links)

In Galaxy SIII I made one test, results (27.85/10.69/16ms) next to the router. I made the test two times in Galaxy S4, reaching (30.41/8.52/25ms) at its highest point. When I walk away from the router (10m) the speeds on Galaxy S4 drops to 3 Mbps.

I tried all. Stock ROM Kitkat and Lollipop, official PHE ROMs, JFLTE-GPE, Cyanogenmod, different modems (current i9505XXUHOB8)... Is this a hardware failure? What's happening?

If you need more information, please feel free to ask!
Indeed, I'm spanish. I probably made spelling mistakes, I'm not an English expert, please do not judge me harshly! :laugh:

Thanks in advance!
