No matter the time of day, .40 Mbps is "typical" for download, .20Mbps for upload. That's on good days. I'm aware of all the factors that affect speeds, I just felt the need to vent about it for once.
I live on an island in the puget sound in washington state and 3G reception here is horrid. And that's after they've made some upgrades to our towers. I really don't understand why our service isn't better considering I live within miles of a major navy installation (Whidbey NAS).
Been on Sprint's Everything Data plan since August 2010 with my EVO 4G, which also requires the additional $10 charge for 4G capabilities (the nearest place I get 4G reception is over 30 miles away). I feel like I'm really having it stuck to me in the pocketbook.
If I don't have WiFi reception wherever I'm at, I typically wont even bother with 3G unless I have to. I'm more likely to just leave it off to save battery life.
Okay I'm done ranting, thanks for listening.

OK I have even worse speeds. Like .2 down at my house. Try this hack, it makes you phone use verizon 3g as roaming:

My speeds are now BLAZING fast. Try it and report back!

I understand your frustration but i only get speeds like that when i get to work and everyone else shows up(2000+ people).
I am in a plant with a big project going on and it never fails at 6am the speed starts to plummit and stays that way all day. Until everyone leaves of course.
I feel for you putting up with that every waking moment though.
And please do respond on if you use the verizion hack, if it helps or not.

I beat you guys. 31kbps. That is .031mbps

I had almost decided to move on to another carrier for the same reason. I looked at www.network.sprint.com and it showed a data speed upgrade withing 6 months. Didn't know if they would come through but they did 2 days ago. Now is decent.
Btw...check that site. For weeks my data was crippled worse than it use to. Maybe because they were working on it I guess....but now is good. I guess patience is key.
......or a booster.
via EVO.

Site doesn't work.

Same here.

I don't think you are the only one. I came to this forum today to see if anyone else was having this issue. I'm also in Washington (Bellevue) and I used to get about 1,000 kbps and decent reception. Lately I'm lucky if I have 1 bar of 1x speed. My speeds are just as bad as yours. How is your signal strength?

Did something happen to 4G service?

It is much better than it was in the past few months. What's going on?

Pretty much the same for me: average (NYC area). CM10/LF2 Crespo modem. These speed tests were run in early AM on a weekend morning , with different servers used so are pretty much the ceiling of what I am getting in my area. I fully expect to drop to sub-2 MBPS d/l in the afternoon. I really hope that Sprint proves me wrong once LTE goes live, but this is bottom-of-the-barrel slow when it comes to 4G.

Yeah, I hope it changes for you and everyone else. I was thinking about changing to crespo myself but since the fc09 is not doing so but I decided to stay with it.

Me smells network vision in nyc! Wish I had lte to test it...3g was never this good, I've been running 4g since day 1 because the random times I had to use 3g it wasn't worth it.it would barely hit half a mb with almost 200ping...but today lol that's pretty crazy.

4G likely depends on the area where you are (proximity to towers, saturation, indoor vs. outdoor etc). In a few places in Manhattan, I could pull as 7-8 mbps; generally, 1.5-3 mbps is the norm - when you can get it. Indoors, can hardly ever connect to WiMax and it frequently drops when I do. I hope NV LTE coverage will at least attempt to approach VZW LTE. Wife's Verizon SIII nearly never drops connection to LTE...
3g indeed seems to have improved. Today I pulled 2.2-2.0 MBPs down on 3g in an area where in the past I could not get more than 1.2 tops... don't know whether to attribute it to Network Vision (which would be a great thing) vs. Crespo modem speed improvement. I also think it's Network Vision as I hadn't noticed a huge speed improvement with Crespo vs FC09 in the past (only moderate).

Poor and Spotty Verizon reception since I got the phone Oct 30th... Help?

Since having this phone since last week I've noticed reception that is worse than my previous Verizon Note 3. I live in a spotty/poor area for reception but it has been worse than ever before now on the 6P. Maybe something in the way I have it setup could help....maybe? At my house I never get 4G (even on my old Note 3 all I ever had was 3G) and at the office I used to get 4G on my Note 3 but now I only very occasionally see it show LTE above the bars at the top of the phone.
I've tried switching between Global, LTE/CDMA and LTE/GSM/UMTS under the cellular network settings and Global seems to return the best reception for me. What should be the best setting here for Verizon?
I have "Data Roaming" off; should it be on?
I have "Enhanced 4G LTE Mode" on; should it be on or off?
"System Select" I have on automatic; good?
"Access Points" screen opens to APN's which I haven't touched because I have no idea what that does...any help in there???
Having used my phone for a while now I can add that I occasionally will see several bars on the reception icon at the top and then it will just vanish and show no bars. Usually my reception would bounce up and down a bit but on this phone it seems to plunge or skyrocket sporadically.
At the office (where I have better reception) I will see very good signal strength around -73dBm 8asu at times and then at other times its -117dBm 1asu or worse. At home its almost always -110 or worse...
Any thoughts on anything I could try to change to improve things or am I just out of luck with a weaker radio in this phone verses my old Note 3?
Thanks

Here's a screen shot of today's reception at the office...

I am also on Verizon and in my house the cell signal is comparable to that. I think there is just bad coverage in my neighborhood; when I go towards the city center it gets better.

I just sold my Verizon note 5 got the nexus 6p, and the 6p gets better reception

How is the screen on N6P compared to Note 5?

You might want to try turning off Enhanced 4G LTE Mode. The Enhanced 4G LTE mode turns on VoLTE. If you don't have good LTE coverage, then you won't be able to make calls reliably with VoLTE turned on.

I agree with your points. I too want to figure out which is best.
This was my battery life on the first day I got it, 10/29. I had the best SOT performance when I was setting it up. Everything mostly on. Realized my coverage sucked when I saw others.

AT&T Galaxy S8 and S8+ signal Strength problem?

Can some one give me some opinion here, please
I pre ordered a galaxy s8 back to two weeks ago, got the phone on April 20th,first thing i realized is that the signal strength is very low on the phone, compares to my Mate 9, same location, same time, same SIM,
the galaxy s8 always has 10-15 dbm higher than i got on the mate 9. and it looks like it drains my phone battery faster too.
So I thought i had a bad unit, took it back to Bestbuy (suck it up for $35 dollars restocking fee),returned and bought a galaxy S8+, it acts the same way. same result, no matter where i am.

SO i have both the AT&T galaxy S8 S8+ doing the same thing. I was wondering , are all the galaxy s8 act the same way?
borrowed a Verizon version of Galaxy S8+ from friend of mine, do the testing, it get the numbers just like how my mate 9 runs.
so it only happens on the At&T models. any one has any idea??thank you in advance.

Mine S8 plus 110 db and my old s5 did 85db, measured with Open signal. Supposedly they lower the radiation and power on purpose.

I think that's true, I don't see any call dropping or slow Internet access. I can easily get 60 mbps on download even with only one bar showing. But I guess the bar is not really for the LTE signal .

Decibel is logarithmic unit used to express the ratio of two values of a physical quantity. I wonder what is the reference value? Logically you would assume it is the same and somehow standard everywhere , but you could be wrong quiet often. To have difference of 18 dBm make me think maybe they're not measured exactly the same way. I could give 100's of examples of such things happening starting with a gallon, but best would be to go to area of very week signal (basement?) and compare actual performance.

Samsung probably forgot to translate RSRP from RSSI (the difference is around 14dBm). If you're getting the same speed, it's just the way the signal strength indicator is displayed instead of the modem being actually weaker. That, or you could be connecting to a farther away tower.

Decibels (dB) is certainly a measure of ratio between two quantities. However, dBm specifically is used with reference to 1 mW (milliWatt) of RF power. ( 0 dBm = 1 mW ).
dBm is used so that there is a common reference for the actual physical RF power level, and so that the energy levels are agnostic of the system impedance. With that said, there is many other parts of the system that could affect the transceiver performance: Data converter SNR in the front end, signal processing quality, etc... The other thing we don't necessarily know is at what stage in the front end is the power level being measured.

Is it possible the phones are connected to different LTE Bands? If one is connected to a higher frequency LTE Band it could have a lower signal reading. I'd confirm this using an app like Network Signal Guru or accessing the phone's service menu.

Having a similar problem with my G950U - the unlocked USA version - on T-Mobile. My problem only happens in certain buildings, though, and is often a completely lost signal as compared to other phones with a 4G LTE signal in the same spot. I posted about my issue here: https://forum.xda-developers.com/galaxy-s8/help/s8-signal-loss-buildings-phones-4g-lte-t3660313 and with more detail, here: https://forum.xda-developers.com/galaxy-s8/help/galaxy-s8-unlocked-sm-g950u-maintaining-t3680887

T-Mobile 6T keeps losing network connection

Is anyone else having an issue with their network connection? There are random times where I open the phone and I can't get anywhere. Apps just spin and time out saying no network connection. Although, the status bar still shows 4G LTE.

I have an unlocked 6T, using it on T-Mobile, and I was getting lots of data connection dropouts, not exactly how you described, but I would go from all bars to zero bars, then it would reconnect after 5 seconds or so. It's seemed to get quite a bit better since I turned off WiFi scanning for location purposes even when wifi is off. Can't say yet that it's fixed but it's been all good for hours now. Good luck with your issue!

I'll try that. I really want to love this phone, but I've had a few issues after only 2 days that I never once had with my LG V30.

Same boat here, I love this phone and want to keep it. Seems to be better but fingers crossed. I had a V30 as well

As soon as Oreo hit the V30, I actually had network issues there too, kind of like what you described for your 6T. seem to get better after a couple of updates for me

Unlocked on T-Mobile and no issues whatsoever

I noticed I have connection issues as well. I'll close out whatever app is having problems and restart the app, but it's over multiple apps. So I'm not sure, what's causing the drop outs

This is an issue with T-Mobile's band 12. Check what band your phone is on when it does this, LTE discovery app can show you. If it is on band 12, that means the tower is congested.

Thanks for this, this used to drive me nuts on my T-Mobile V30 in Los Angeles, especially once the phone was updated to Oreo for some reason. Now on my OnePlus 6T, I was getting a lot of times where the signal just completely drops out and then reconnects usually within 5 or 10 seconds.

Cruised thru a couple different towns and had no issues with T-Mobile today

So I've been tracking the issue, been having lots of dropouts this morning here in Los Angeles. From using the app it seems like I'm usually on band 4, but when the connection drops out and reconnects, then I'm on band 2, but will be back on band 4 after a couple minutes. Do you think this is definitely the network and not my phone, I need to determine whether to send the phone back, which I don't really want to do.

Yeah that's network. The towers are kicking you off because it's congested. Unfortunately, T-Mobile doesn't have the capacity to handle the huge increase in subscribers that they have gotten over the last year or two.

Ok thanks ? Makes sense

I am experiencing the same issue not only in US but also in other countries.

You can also use signal spy to check with bands you're currently receiving, and it'll give you a good idea of what kind of coverage you're looking at. It'll specify the signal strength, type of band you're currently using, and more. Highly recommended if you want to know what your signal is looking like.
