[Q] Is there any way to make sure my 4G is functional without being in a 4G area?

I'm pretty confident the warranty on my Evo will expire before 4G comes to my home area, despite the salesperson stating that it would here prior to 2010 year-end, Sprint has not even announced plans for my city yet.
So, I just wan to make sure it's working without having to travel 3 hrs minimum to test it on an actual WiMax signal.

This will check to make sure your RSA keys are intact. Not sure of a way to actually test the signal without 4G in your area.

Mail me your phone and I'll test it....
seriously though, Your keys can be in tact and all but it could be possible 4g still doesn't work... It's pretty much impossible to know without putting yourself in a 4g area.

I've actually backed them up already, but only after I rooted, nand unlocked, and install a custom ROM. I wasn't aware I could do this before I did.
I ran the grep command and the output was in order, but from what I understand, that output isn't a sure-fire way to insure that it's working.
Any other thoughts?
EDIT: Just noticed that we're both waiting on the same location for 4G.

I'm assuming you're in an area covered by 4G then? You know that the 4G is working on your phone, right?
Let me ask you this, then: what happens in your phones 4G settings menu when you're not getting a signal? Will your phone scan for a few seconds, then after not finding a signal, look like this:

4G stays on but says disconnected after a few seconds?

Yeah, I'm actually in Tampa right now visiting family and got to test 4G for the first time. It's nice but I dont consider 3G in the Detroit area to be that bad. Plus wifi is everywhere and much better on battery life.

Horrible 3G speeds should i be concerned?

I'm having horrible 3G speeds at work here and was wondering if anyone else was having these issues? It shows i have full 3G bars yet when i run speed test i'm consistently getting only around 100 Kbps, I'm not sure if it's the service or the phone.
Anyone else noticing ridiculously slow 3G speeds?

Not sure. Here are my Verizon 3G speeds.

Here's my past couple ones on 3G. I dunno whether or not to call Verizon about this or not.

Why wouldn't you call Verizon about it? If it's a network problem, they could tell you. If it's a defective phone, they could help you with that as well.

I always get horrible 3g speeds at my job... similar to what you are seeing even though the signal is good. I think some towers are slower then others.
Were you getting better speeds before this phone?

Those look identical to Sprint 3G speeds.
Where are you located?

I would give verizon tech support a call, maybe they can provision the phone again and and maybe that would help. You're sitting in a good 3G and 4G area, there isn't any reason to get those kind of speeds you're seeing.

2 foot wifi range with brand new Galaxy Nexus

So i picked up a Galaxy Nexus, was brand new (almost, package was opened but never used, checked the UPtime on the battery was only mins..) anyway. im and pretty certain it wasnt hacked or anything. it was just someone trying to sell their new free phone from a contract. model number i9250m
So i brought it to my GF's house, where i have never had any wifi issues, it would show normal good bars, connect and then get the IP.. internet would work fine, then all of a sudden, nothing.. turning Wifi on/off again, would sometimes allowe it to reset, but still, nothing more than 20 seconds... when i would use it in the bathroom (router is in the landlords on the other side of the wall.) it would work fine. No other devices in the house would give any issues over wifi...
SInce it was only 4.0.2 i though i would upgrade.. so i tried the nightly build cyanogen mod rom, cm-9-20120602-NIGHTLY-maguro-signed.zip still the same issue, even at my house, nothing, unless im 2 feet from the router.. 4-10 feet and a wall, no luck at all.
after some reasearch, they said change it to 5.0 ghz from 2.4, using one or the other didnt really change anything, (i think 5.0 didnt even work) i installed wifi analiser, here is what it is showing

with this reception, wifi only works from 4 feet. and is not that stable.. when it is connecting, it is super fast, but not consistant at all.
I have changed teh channel from 6 to 11, since wifi analizer said it was a better one..
I am using AWS (wind mobilicity) network. ANyone have any input or help?
thanks

i just replaced my new gnex for the very reason you stated. the phone also got very warm while charging and took grainy pictures.
so far the replacement is doing all 3 things much better.
i would suggest trying to get a replacement.

the funniest thing, i have 2 boxes (internet with built in router) and a seperate linksys, (used as a switch) i just disabled wif on the switch and everything works! that doesn really explain the problem at my g/fs house,
this was weird, because i was hacing the same issue with my Nexus S and an Ipad.. hopefully i dont have a faulty Wifi.. thanks for the help..

That's weird. You have super strong signal. I don't know why it isn't working. Haven't seen many posts about this issue.

Signal issue with 1 gnex

Hey there guys since January me and my brother plus other family members switched from AT&T to Verizon , until couple days ago my brother started seeing very low signal on his Galaxy Nexus.
We live in NY , Queens he lives 10 minutes away from me it's different city but it's a 10-15 minute walk.
I will post two screenshot from same application to check tower status and signal strength.
First One is my screenshot

Second one is his
+1 his
Now question is this is def a Verizon problem , how do I get them to help me with this? some sort of Booster or anything : please also note that adress on my bill is assigned to me not him.
Thank you !

Sounds more like an issue with signal in his house or he may be just far enough away from the tower. Have you compared your phone's signal at his house?

I have not actually , but it was just fine since January he even had 1 4G bar , so in case that it's Verizon's fault how can I make them give us a signal extender any ideas?

Umm ask the big man upstairs for a miracle? I've never had any luck getting VZW to admit fault with anything...

Hey guys I have an interesting update , it seems there might be some sort of signal jammer inside his house he has no idea what it could be , as soon as he walks out of his house to his yard he gets perfect signal -> once he goes inside the house almost dead zone.
Question is now , how to look for signal jammers?

doesnt it make sense that the signal gets weakened inside. like those crazy walls and stuff

[Q] Constantly losing network connection

Let me preface this by saying this phone was damaged. I had to replace the digitizer.
I just started using this, and flashed Pacman's latest nightly on the phone before getting my SIM, so I can't confirm or deny whether or not this works on stock. That would open up another question entirely.
My phone is completely losing all connection to the AT&T network almost anywhere indoors, and in a lot of places outdoors. I do however get complete, fully functioning connectivity in some locations.
For example I picked up my SIM from the AT&T store today, had no connection inside the store. Went outside and immediately got LTE connectivity, placed a call. After driving across the street to eat the connection completely dropped again. It returned as I got close to my job's office, stayed at full strength and then dropped off again once I went inside the building.
It did not return at any point while I was inside the building. After leaving it regained its full strength and remained at full strength, including through a speedtest, until I came inside my apartment. It has not come back since, including when I went out into the parking lot, where it previously had a strong connection.
This makes no sense to me whatsoever.

Went back to stock, so disregard the earlier part of my post about not knowing the best way to do that. I'm on raw 4.1.1 now. Still have the same issue. This is the phone status page.

Are you on the latest stock build? My Note is starting to do the same thing now on the latest stock build

No, I reverted all the way back to the original shipped build, 4.1.1.
I was using the latest baseband though when I had AOSP on there. Both did same thing.
A few observations since my first two posts. The signal strength does change of course.
Going near windows in my apartment makes the DBM go into the -90s and the asu go anywhere from 2 to 8. If the asu goes above 10 I get 3G and brief connectivity. Yet to see what the signal strength is on full LTE.
Anywhere in my apartment with no connectivity though is between -110 and -115 dbm, all with 0 asu.
