WG3526-P \ EM7565 slow speeds

Post by 1337Jess » Tue May 28, 2019 11:54 am

Hi all,

I setup a WG3526-P with a EM7565 modem using a Verizon Unlimited (grandfathered) SIM. I am currently on Firmware wg3526-GO2019-03-10 however I have not updated the firmware on the em7565. I am 3.4 miles from the cell tower and there is a large amount of vegetation in the way. I am only seeing about 6mbps down and 2mbps up at the max on the WG3526. This is the fastest I have seen it speedtest. It has gone as low as 0.7mbps down and 0.1mbps up at times. I am trying to find out why the speed is so slow. I read that others are getting much better speeds and they are twice the distance as I am. I have set the TTL to 65 - 117 but that didnt change anything. I am still seeing extremely slow speeds throughout the day. I am not sure where to look to see what the issue is. I have a Galaxy S6 Edge phone also on Verizon and I have noticed that my phone seems to have better (faster and more steady) connection.

P.S. Something else I noticed is the 3g/4g LED on the WG3526 never comes on or blinks. Is it supposed to from the factory or is that something I have to setup?

Your antenna stats show the Primary Carrier on LTE is Band 13:

Code: Select all

System mode:   LTE        	PS state:    Attached     
LTE band:      B13    		        LTE bw:      10 MHz
The Secondary Carrier shows to be LTE Band 4:

Code: Select all

LTE SSC1 state:INACTIVE    	LTE SSC1 band: B4     
LTE SSC1 bw  : 10 MHz  		LTE SSC1 chan: 2100
The Primary and Secondary carrier relates to Carrier Aggregating of bands (13/4 in your case)

Band 13 operates on the 700MHz while Band 4 operates on the 1700/2100HMz.

The lower the frequency, the larger the wave length, and the higher its penetration and power--especially over distances and through foliage.

On the other side, the higher the frequency, the shorter its wave length, the greater its absorption and the more difficult its penetration.

We can see this in the antenna signal stats:

Primary Carrier, Band 13, 700MHz:

Code: Select all

PCC RxM RSSI:  -72		PCC RxM RSRP:  -99
PCC RxD RSSI:  -69		PCC RxD RSRP:  -96
Secondary Carrier, Band 4, 2100MHz:

Code: Select all

SCC1 RxM RSSI: -94		SCC1 RxM RSRP: -114
SCC1 RxD RSSI: -92		SCC1 RxD RSRP: -112
This hints that your speed issues may well be related to subpar signal strength for your secondary carrier (Band 4).

We often see this in foliage conditions where higher frequencies are struggling to penetrate trees. Under a heavy foliage condition would also make band 13 popular for other devices in the area as well--which could lead to tower congestion.

The rest of your signal stats look good (refer to the chart below)

Also, when changing your TTL (65, 117) you need to do a power off- Power on (i.e., hard reboot) to be assure they take effect.

Thank you for the feedback Jim! In your opinion, would setting up a 700-2700MHz WiFi 4G LTE 8dBi Directional MIMO Antenna be worth while or would that be wasted money?

Also, I noticed the 3g/4g LED on the WG3526 never comes on or blinks. Is it supposed to from the factory or is that something I have to setup?

That would be hard to say. Generally, if you can improve your signals and the quality thereof, you can improve your speeds.

It is possible to improve your secondary carrier stats, and possibly pickup the third carrier bands for 3 x CA if they are available on your tower (where at the present time, you are only receiving 2 x CA).

That is firmware driven and may be configured--although I personally have never messed with it.

I see. Sadly the connection is not very good at all today. I can barely get any work done which is obviously not good...

Is there a change in the weather (i.e., rain)? If you are in a foliage environment, rain has a significant effect on signals as does the time of day (prime time = congestion)

It's been really dry here for the past week. No real weather changes. One thing I am noticing though is when the internet feels more solid it shows it's connected to B13. When it's CA's with B4 is when it slows down to a crawl.

Speedtest on B13 only, shows about 4mbps down
Speedtest on B13 with CA to B4 shows 0.8mbps down.

I am at a loss. I received and setup the MIMO antenna and even though it seems my signal strength and quality has gone up, my speeds are just atrocious. I am consistently getting between speeds as low as 0.3mbps down. I have no clue what to do here...

Your signal stats look to be good enough to get at least 50mbps town.

I'd suspect tower congestion based on your RSRQ values, and my knowledge that Verizon tends to be more overloaded than AT&T even though Verizon has a much wider coverage area typically.

Those seem like odd speed results for those stats. If you are willing to step through this, maybe we can narrow down what is going on and ensure it is a congested tower, which it very well could be.

How are you testing your speeds? What speed test software are you using and what is it running on? Although real world workloads are slow too, it might still be good to consider the test software. How is the machine it is running on connected to the router?

How is the modem connected to the router. Is it plugged in inside or connected externally through USB?

Have you tried the sim in your phone to see if you get the same speeds with that sim as your regular phone sim? You said the phone has a faster and steadier speed. What speeds do you typically get with the phone?

Do you have an inverter, so you can run the router off battery power in your vehicle? Taking the system directly to the tower (a couple blocks away is generally better than directly under it, in my experience), could verify if it is tower or vegetation (although your stats seem good enough even if vegetation is reducing your potential).

If you can take the system to another tower, that will help quite a bit in determining if it is a tower related issue or router/modem issue (or possibly a Verizon throttling issue).

If it ends up being a tower issue, maybe there is another tower you can reach inside or outside at home that will provide better speeds.
