WiFi to Cellular Hand-off Slow - Atrix 4G Q&A, Help & Troubleshooting

Is it just me or is the hand-off between a wifi connection to the 3G/(HSPA+) a bit slow? It could be an android thing or Atrix specific but I have no idea since this is my first Android phone. My previous phone, iPhone 4, when I would leave/disconnect from wifi, it would immediately connect to cell network within seconds. However in my Atrix, when I leave a wifi area or disconnect, it takes anywhere from 20-30 seconds to have cellular data connection (arrows under H+).

[Q] Stopping 'H' data connection continually switching to '3G'.

Is there any way to increase the timeout before the connection is dropped on an unused data connection? It seems to me at the moment if you don't use a fast 'H' data connection for more than 30 seconds, it drops to '3G' and becomes unusable, often leading to timeouts as it tries to connect back to 'H' when you try to use it again. It makes for a truly abysmal non-wifi browsing experience that even my old HTC Artemis beats hands down.
I realise this is more than likely about saving battery life but I'd rather take the hit on that and it just connect to the fastest available connection and stay on it until it either loses the signal or is turned off manually. Pretty much like every other phone I have used does.
Cheers.

Very slow wifi

Having issues with extremely slow wifi on my device. If I'm upstairs I can't even connect to my router. If I'm downstairs I connect but get horribly slow speeds. My other devices see like 8 wifi networks in my area, but I see only mine with the s4. If I try to enter the name of an open wifi network I know exists in my neighborhood, the S4 can't even see it.
I tested out disabling security on my router, and my speeds jumped up to normal if I was right next to the router. However moving to other locations in the house I still lose connection. If I turn on any kind of wireless security on the router, the speeds are super slow even right next to the router. In the 600Kb range (I have a 20Mb internet).
Almost sounds like a hardware issue to me. Tempted to bring it to Verizon, but who knows if they even have replacement devices at this point.
EDIT: So I managed to get the device to get fast wifi with security turned on by messing with security settings on my router. But if I do a speedtest right next to the router, I get great speeds. If I walk upstairs, and do another test, it's like I went back to 1997. Suddenly my ping is in the hundreds, and I'm getting 56K speeds. Walk downstairs again, and run it again, BAM fast pings and 20Mb downloads. The GNex gets 20Mb speeds throughout the entire house.
I have the device right next to my Galaxy Nexus right now. The GNex can see my network, and 5 others in my area. The S4 can only see my network.
Could very well be a hardware issue with the actual unit - I don't have any WiFi problems at all here - is this running on stock? If so I would recommend seeing if you get a replacement unit if it helps - if not then I would ask what settings are on your router? is it 5ghz (i have had problems with that on ALL devices)
Are you using a case or custom back cover? If so try it without the case/back cover.

I'm running stock rooted.
I'm using a case, I've tried it without and it makes no difference.
My router also does 2.4ghz and 5ghz, and I've tried both and it makes no difference. I generally use the 5ghz, because the signal is bit better.
The oddest thing to me is that this thing can't see a single other wifi network in my area. My other devices will see multiple wifi networks.
Go into your router and disable (uncheck) the WMM option. Odds are youre having the constant connect/disconnect from some routers, especially but not limited to DLink DIR-655 and DIR 855 models. The disconnects and reconnects are quick enough that you sometimes won't see the wifi icon disappear and reappear.
I had the issue (i have the DIR-655) and unchecking the WMM (Wifi MultiMedia) fixed the issue.
I have that option disabled.
I really think this is just the wifi radio being weak compared to my other devices. Not sure if its a defect, or just the way the verizon s4 is. The performance is fine in the same room as my router, or even in the room directly above it. In the furthest from it in the house, however, the S4 just can't get any connection over barely 1 bar, and the signal in wireless signal info is horrible. Not being able to see other wifi networks in my area is the most telling thing to me. Even if I walk around my neighborhood, I can't see any others. Maybe if I walked right up to someone's house I could, but I haven't wanted to look pervy, so I haven't tried that. :laugh: At this moment my Gnex can see 5 other networks sitting in the exact same spot as my S4. The S4 just sees my networks.
Yeah sounds like yours is defective. On mine I can see networks from all around my neighborhood. (~5 of them)

So today I finally came into work after being off for awhile, and brought my S4 in for the first time. We have open wifi at work everywhere with multiple access points per floor, so no matter where you are you should get 3-4 bars of wifi signal. From my desk where I usually get the full four bars on my GNex, my S4 gets 1 bar of wifi. Doing a speedtest, I get 2000kbps down, 872kbps up. My GNex gets 35Mb down, and around 25Mb up on the same wifi connection. So yea, there is something seriously wrong with this thing.
Damn I guess I need to flash back to stock and take it in.
I took took mine to Verizon and they swapped it out. This one gets a great wifi signal. The capper was when I was in the store and their display phones could see all the local wifi networks, and mine couldn't. Mine was barely able to connect to their instore wifi. New one works perfectly.

Getting VERY poor Wi-Fi signal and/or intermediate connection

Sigh...thinking my phone may be broken or something.
When I'm in my room I get full signal (Linksys EA4500 Wireless-N router) but if I step into the kitchen which is like 10 feet away (and it's open air/no doors between my room and kitchen) I will either completely lose signal or it will switch between cell signal and Wi-Fi.
There is NO way it's my router as many other devices in my home work perfectly fine and my router is bad ass. So what's going on with my DNA? Something doesn't seem right at all. Plus I've noticed even my cell signal will sometimes just shut down (an "X" next to the bars) for like 5 minutes at a time. I'm using it with Straight Talk through AT&T so I don't know if that's the issue but it's dropping signal in places that my last phone worked perfectly.
Just odd connectivity. Anyone else having issues with their Wi-Fi at all? Thanks!

Micromax Yureka : WiFi problem ( Avoided due to poor internet connection )

So I bought this phone a few days back and I'm trying to connect it to my home WiFi network. The problem is that the phone dismisses the connection as poor connection but the signal strength is actually excellent. All the other devices connect fine with my DSL router. And also the avoid poor connection is kept off, but it still avoids the connection. Is there any solution fo this? My phone runs on Kitkat OS and CM 11.

Wifi roaming - 'xfinitywifi'

On my previous phones, I'm used to connecting to xfinitywifi if I get a strong signal (i.e. coffees hop), but having to disconnect later as it causes so many issues while driving (grabs signal for a second, but doesn't get data, eventually disconnects but meanwhile I'm left without data)
I noticed that on the Nexus 6p, the phone actually 'roams' on xfinitywifi pretty well. I drove 3 miles between a restaurant and my house last night and it managed to continuously grab different xfinitywifi signals and keep me connected. Impressed.
I'm running ingress on my phone which uses data - so I know it's actually working - data disruptions showup right away on this app (it only happened once for a few seconds during my drive..)This is in San Francisco btw. Might keep xfinitywifi as one of my wifi connections on this phone
-mark
Did you have any of the WiFi toggles enabled under developer options to enable aggressive WiFi to cellular handoff, or mobile data always active?
I have the opposite experience with my 6P, I need to turn off wifi because it latches on all the time and often the signals aren't strong enough and i get no data. I can tell it drops constantly as my VPN connects and reconnects all the time and kills my battery.
