MIFI 4510l speed issue

Mfif 4510L 4G LTE speed has deterioated to .25 to .40mbps from 1.5 to high of 6.2mbps. anyone else experiencing this issue. I've done battery pull, sim removal with no positive results. filed a trouble ticket with support but no response to date. I have excellent signal and -68db to -73db most days. Any suggestions will be appreciated.

Hi Joe,

Performance problems like the one you listed should be correctable with the various levels of resets. The only other reset that you did not mention was restoring the defaults by pressing the reset button next to the battery. I have found that the reset button can produce different results than just powering down and removing the SIM.

Level 3 Reset

Power on the MiFi
Remove the back cover
Press and hold the Reset button next to the battery for 10 seconds
Watch the MiFi E-Ink display to see if all the icons are displayed
Release the Reset button
Reassemble the MiFi
Test your connection

Try out these steps and let us know how it goes.

Hi John,

Gave it a try this morning; no improvement, but thanks for the suggestion. I've tried multiple setting combinations none seem to improve the service. It's either the device or network in my opinion. I'll give VZW a couple of more days to respond to trouble ticket but seems from looking at community postings 4510L is an ongoing problem with issues. At my current abysmal speed anything beyond searching web or email is a joke and certainly no where near the stated speeds.

My local phone company has a variety of plans with excellent mbps speeds whcih appears to be my best alternative. I will lose portability when travelling but with host of available wi-fi hotels it shouldn't present a major problem.

Again, thanks for the suggestion and hope you are having a better experience with the service.

Joe.

Those are some poor numbers, especially for 4G LTE. If the resets are not helping then there may not be anything else to try besides replacing the device or canceling the service. Your signal strength does not look like its an issue so a antenna/amplifier will not help. There are no other configurations that you can try to improve performance either.

Unless VZW can confirm there is a service problem in your area then the next step is hardware replacement. It sounds like your speeds were acceptable at one time so lets hope they do the right thing and replace your hardware under warranty and free of charge. If not then discuss with VZW your options for terminating their service with a discount for the time you were not able to use the device.

Does it happen at all hours or just doing Peak Times? Also how much data have you used? Verizon has been known to throttle customers.

WORKS great at 3:00am but during the day it's abysmal. Contacted executive office and the network engineers are working on it but I beleive it's spectrum, capacity or traffic whatever you want to call it. I would love to stay with VZW but not at these speeds. We'll see what happens but I'm not holding my breadth, it's clearly not the device but the network!

John_Getzke

VZW has started to enforce Optimization which is not the same thing as throttling. If you were throttled then your speed would never get better and would stay that way for 2 months at a time.

What you described here sounds more like Optimization where your bandwidth is de-prioritized to the bottom of the totem pole. You basically get whats left for bandwidth on your local towers. VZW would have contacted you to inform you that you were being optimized. Optimization should not effect 4G LTE devices such as the MiFi 4510L. Optimization is intended for unlimited 3G only contracts.

John,

Thanks for info never notified of optimization and 3G phones working fine except for certain spots when traveling that must be low signal areas. As for Mifi 4510L works fine in the wee hours of the morning but once more people would be accessing service speed drops below unacceptable. VZW engineers supposedly working on problem, no updates! I really think it's a traffic, capacity, spectrum or whatever correct terminology is for the problem. Local phone company offering 10Mbps for less than VZW for a year, leaning to that service. Lose portability but gain ability to adequately download software, utilize YouTube and gaming opportunities. Reports from many neighbors support reliability of phone company speeds. Maybe someday VZW will deliver reliable 4G LTE in my area. We were thinking of upgrading phones but with this problem think we'll stick with 3G phones for now.

Appreciate the update, hope all going well for you.

Joe.

The problem you describe fits me to a "T" also. We have no 4G service in my area. The MiFi was working good for the 30 day free trial but has now started giving problems: Once I am on line, it (the 4510L) will just stop/freeze sometimes for longer than several minutes. This device is a research killer. It doesn't work much better for simple e-mails. My 3G phones operate OK; have used them all over the country. Like you, I think I might go back to cable modem - never had a problem with throttling or any other degraded condition. On-the-road, there are plenty of free wifi hot spots that I can and have utilized. Please post any fix you might find.

Thanks,
Catfish

I've had the 4510L for a month and a half. My speed problems are much like you describe. Started out decent but dropped off. Here are some additional symptoms I have discovered:

* 4510L reboots constantly. I had one instance where my device rebooted 11 times in 5 minutes. No way of telling what was causing this because the log files flush out with each reboot. A handy feature when you a wireless carrier and need plausible deniability.

* Dormant state - Here is one log file showing all the dormant states that occurred in a matter of minutes:

Here's an example of the connectivity issues I was having - it was so bad that the device eventually stopped trying a 4G connection and went into EVDO:

Just for FYI - I also watched the modem status log as well and refreshed that constantly. The LTE Signal was overing around -71dB and the SINR LTE was between -4 and 9dB

So much fun to deal with when you are in a meeting with executives and your display is on the projector.

I sympathize, nothing new if over a week; have phone company coming on Monday to install their option. If it works as they say it will then I will cancel this service because it really is useless for any serious internet or download usage. If something miraculous happens I'll update my post. Also, phone company is an unlimited plan no throttling or caps.

joemmcghhi

i am in 4G LTE area have not experienced the rebooting as such but do have dormancy issues at times and drop offs to limited availability even though signal is still excellent. I was hoping they wuold resolve problem but almost two weeks since contacting VZW support and over one week since Exec. Office got involved. my plan is to test phone company set up and if speeds are as advertised cancel my mifi service. Hope you have more success with your problems.

redgoldwing

I hate to say it but you all are making me very nervous. I'm supposed to be upgrading my Pantech UM150 to one of the devices you all are having issues with. It is still being shipped. My issue is that the last couple of days, my servie has dropped off to an almost worthless state as well. It used to be fine. I think they are throttling some of us 3G unlimited data plan users to get us to move to the 4G devices. All your comments don't have me feeling very comfortable about making that switch.

John_Getzke

Redgoldwing,

If you are a 3G unlimited customer then you are vulnerable to Optimization and Throttling. The two should not be confused with each other but they are a very real possibility. VZW claims that anyone over 2 GB of useage per month is considered a heavy user and has the right to Optimize thier connection. Only those who are within the top 5% of data use are eligiable for Throttling.

You can confirm if you are being throttled, optimized by checking your connection speeds at an unusual hour. If they get better then you may be getting optimized. If they do not get better then you are either being throttled or your device is having a technical issue which can be fixed by resetting or restoring the defaults. VZW should not be throttling or optimizing anyone without notifiying them first. You can always call VZW if you suspect that this is happening to you.

joemmcghhi

hope you have a better experience than I've had; They couldn't resolve my problem even when I went thru Exex. Office so I pulled the plug today and went with a plan from my local telephone company. Think the issue is one of local conncetivity so ir'll probably depend on bandwidth & capacity in your location. I gave up portability but can now download software and watch live events without stutter or buffering. Good luck!
