Weak wifi - Nexus S Q&A, Help & Troubleshooting

I'm on cm9 on my ns4g and I get weak wifi even at 10 feet from my router. I have tried all kernels and most roms (ics and gb) and all radios. Anyone know a fix

are you serious ? 10 feet , like 3,4 meters ???
may i ask , how many walls in this 3,4 meters between you and router?

What do you speed test at? I often show 1-2 bars of wifi less than 10 feet from my router but you wouldn't know it downloading anything or doing anything over wireless.

Extremely slow connecting to wifi on CM10 (stable/nightly)

I have an HTC One X (AT&T) and I am having a pretty slow time connecting to wifi around the house and in other places. It is a WEP connection at home, and several other android devices have no issue connecting (my dad's Nexus S running CM10 takes 3 seconds) and my iPhone 3G takes 2 seconds to connect, while my HOX running CM10 takes anywhere from 60 seconds to an entire hour, usually falling between 15 minutes to 30 minutes to connect. Once connected, data speeds are normal and the connection is stable. I've had this problem on CM10 stable and the latest nightly, before and after a wipe and clean install. I don't believe I have been having this issue the entire time I've been on CM10.
NOTE: I restored my Cleanrom backup (4.0.4 I believe) and the wifi connects in 2 seconds to the same router without fail every time, over and over again.
Is anyone else having this issue? Do I need to flash a custom radio or something?

You guys get a cookie. They were both 2wires. Is it just the router is a POS and there is a connection lag or something?
Something with those routers are preventing cm10 based ROMs to latch on to its wifi. Sense ROMs connect instantly, and I bet if you use someone else's wifi that isn't a 2wire it would connect instantly. Join the clan bro.... :thumbdown:

Bastards. Good thing I'm in IT and I have like 5 more routers. That makes sense, because when all this started was when I came home for Christmas. Should be gone again in a few days. Thanks guys.
Heyyy sense you mentioned using other routers, would you know of any other routers compatible with uverse? Regular DSL routers would work?

My friend has a cisco one but he also has a new 2wire box. They are both transmitting wifi and one says uverse on the side. I think the AT&T guy was high when he set them up, because I argued with their family that they had 2 wifi sources and they were like no we only have 1. You could always disable wifi in the 2Wire and hook in your linksys or whatever into one of the ethernet ports on the back of the 2wire. That's what I would do.

Wow that explains why I can never get WiFi at my friends house when it works on his iPhone and his dad's galaxy note
So what is the solution? Surely there has to be a workaround?
Not that I can find.. I've been reasearching and cant come up with much.. a guy gave me a tip with the default router passwords but mine won't except it bc its too short.. I know I have to go into settings and change some stuff but haven't yet. The address is on the router to access settings but I keep forgetting beings im working on sense lockscreen mods

Bad WiFi speeds

On my Nexus 5, WiFi is fine downstairs near the router (BT Hub 3).
But upstairs in my room where I usually am, speeds are very very slow. Less than 1mbps. On my N4 & N10 speeds are fine in my room like the rest of the house, but my nexus 5 is getting bad speeds.
What is the issue? What can I do? I've tried changing WiFi to 2.4ghz only but no such luck.

T-Mobile weak LTE

Ever since Ive had my nexus 5 Ive noticed weaker lte signal on t-mobile. I have a nexus 4 that has the .33 radio that i flashed and i get lte in more places & better speeds. Both are using the same t-mobile APNs, for example on my nexus 5 half of my home I get HSPA+ and on the other half I do get LTE i guess I'm just in the middle of two towers that reach me. On the nexus 4 though, I always have LTE In my house and In more areas where the nexus 5 doesn't. I then later flashed the cataclysm rom and thought maybe it would help but nothing, I did find a setting within cataclysm to force lte always on and I get even more LTE service than on the nexus 4, but it takes up a lot of battery. My issue is Im back on stock KitKat and dont have that feature and T-Mobile LTE is just weak. Is it just my nexus 5 or have other people expirenced this too?

I'm located in Forest HIlls, NY On KitKat 4.4, I usually get 3-4 bars, indoors/basement. After updating to 4.4.2, I still get 3-4 bars. Like real estate, it's location, location, location.

Do a search for EFS and Modems, there's a thread that has a link to all of them. Some have said earlier radios like from 4.4 get better signal. I'm on 4.4.2 stock radio and didn't see any change from one to another but that's just me. In Brooklyn and Manhattan NYC mostly btw.

Radios are here:

But there's sparse evidence any are better on LTE specifically. In theory, the latest should be the best. I get 4 bars LTE and 30Mbps d/l, yet get 5 bars H+ and 12Mbps d/l...so clearly despite a lower overall signal strength, my download performance remains perfectly acceptable.

What router are you using (with ac wireless)

I'm planing on changing my router for a new one that has ac wireless. Before I RMA my nexus 5 for that damn WiFi drop issue I thought it was time to try a New router but I would like to know who has a router with ac wireless and if you have any WiFi drop. So very easy.
Router manufacturer make and model.....
WiFi drop yes/no
Thanks

I use a Asus RT-AC66R and love it. Never had an issue with any device. No drops either.

Mine is no AC wireless but its certainly better than those Asus AC High performance routers
what I like is a balance between Coverage and performance a company called Amped Wireless In the USAMakes these types of routers not some cheap china/korean stuff
What I have is this http://www.ampedwireless.com/products/r20000g.html
It's got dual signal amplifiers each antenna port is outputting 600Mw of power that's face melting wifi right there. Most routers don't even output 100Mw. Routers with internal antennas put out only like 50Mw and have no signal noise filters.
So overall my router is a bit overkill but somehow my Nexus 5 manages to drop the connection lol... my other devices don't exhibit such behavior though.
I'm guessing this is software and I'll wait till Android 4.5 comes I have a year anyway from LG to RMA

Did you check what channel your routers using or if there's a conflict with a nearby router on the same channel. My wife's Macbook pro couldn't hold a WiFi signal from 6 feet away yet every other device in our house had no problems. What I did was took the router off auto and set it to use a specific channel that no other routers within a couple hundred feet where using. Now the MBP has been rock solid since. Turns out me and two neibors were all on channel 6. All my Asus Transformers where real sensitive to signal also.

Hey you might have just fixed my Nexus 5 wifi dropping issue 3 of my Neighbors are using channel 6 also. Whats up with Auto on routers defaulting to channel 6. Anyways it seems good now ! :good:

Haha switching my channel also increased the coverage lol the amplifier is now at full 600Ma where it used to be only 350

Try different channels anyway.. Different device radios react to differently to frequencies

It certainly does. You can force it to 2.4 or 5Ghz.
I had to force 2.4Ghz on the phone with my old Wireless G router or speeds were compromised.

Anyone having trouble seeing some AC channels? I had a launch day N5 that had no problem connecting to ch 153 on my Netgear Nighthawk running DD-WRT. I sold that N5 months ago and now have bought another N5. This one won't "see" my AC network unless it's set to a channel under 48. Even wifi analyzer shows that I have a limited 5 GHz channel range. My S4 connects just fine. Do your N5's see higher 5 GHz channels?
See the photo below. I only see my neighbor's wifi 5G network and the graph stops at 44.
EDIT: Fixed it. It seems changing my extension channel has fixed the issue. I now see the network. N5 seems to not support all AC channels listed in my DD-WRT channel settings.

WIFI

Why would every computer in my house show my WiFi speed as around 16 Mbps but my n5 will always show around 5-6 mbps ? My WiFi is supposed to be 19 Mbps with only 1.2 up so the computers are correct. When I download something on the computer and then attempt my n5 the computer will download the file at 1/3 the time the phone will. Thanks to anyone who may know a fix or suggestion.

There are a couple threads that cover this already. Selecting 2.4Ghz or 5Ghz on your phone or disabling mobile data while on WiFi usually fix it.
