I’ve got an issue with slow and inconsistent speeds on the x750.
I purchased it a few days ago as it seemed to be better to use it directly with a sim instead of tethering with my phone on the ar750.
Since connecting it the download speeds absolutely suck - I’m not using a VPN.
It seems to be limited to about 20mb down. Upstream seems to go up to 30 or 40 at times.
What’s with this? I messaged support who said:
" This is due to differences in hardware.
The phone may support CAT11 or CAT18, but the router usually works on CAT4.
If you have purchased EP06, the router can work on CAT6"
Which isn’t very helpful at all.
I have the EP06 version. Surely this can’t be limited to 20mb down???
I’ve 2 Sims and 3 phones, I’ve tried the sims in each phone and get 90mb down and sometimes 90mb up.
But when using the Spitz I’m getting 20/20 tops… I’m not really happy with this considering the price of this thing. I’d expect more performance for that price.
I’m in the UK, I’m connecting to Band 7, which gives me lower latency than band 3 by about 20ms.
Mobiles on 3 or 7 achieve much higher speeds than the Spitz.
Any advice? Is this the absolute limit? If so I’m sending it back for a refund.
dl_bandwidth is on Megahertzs, not on Megabytes, is the bandwidth than Carrier is warrantied to you.
you can use this web site to calculate the speed based on that info:
With that configuration (band: 3, dl_bandwidth: 20Mhz) you can get this results:
Even with your calculations in not even getting those speeds and I am using band 7 as it gives lower latency. So based on that site I should be getting 150/50
I’m barely getting 20/20
I’ve tried different APN settings. It doesn’t seem to make a difference.
The masts that I connect to are about 400 meters away. There’s one to my north and one to my south. But there are other masts closer which are band 3 but I am unable to carrier aggregation on band 3 & 7.
It always comes up as 3&3 - so I force 7 as my phone’s connect to 7 by default and I can get 90/90 on them - I’ve even got 120/50 on them before.
So it’s not my carrier. At least I don’t think it is.
Well, I’m using two different modems over Orange (Spain), a Huawei ME909-521 and I got 20/30 (and is a class 3!) and using a Quectel EP06 I got 50Mbps using two external MIMO antennas and configuring the Carrier aggregation using the AT command:
AT+QCFG=“band”,8d0,1a1880800d5,0
You can get more info here: https://www.ltehacks.com/viewtopic.php?f=15&t=674
For that reason is that we use LTE-A Carrier Aggregation, almost all recent (and decent) phones have modems with carrier aggregation support (> LTE CAT6), which is necessary because all carriers have super–congested cells and you need to aggregate several channels to get a decent speed.
I’m having the same speed problem with TMobile in US. Will aggregation commands work for the Spitz? Is there a newer card than can be used with my SIM to allow speeds similar to my cell phone?
