4G Router slower than Android Hotspot? Please Help

Hey Friends,

I am switching to 4G since cable internet around here in Belgium is very slow.

They just released an Unlimited 4G Data package which i subscribed to. I have 3 Different SIM cards I can use at the same time for Data.

Before buying the routers I simply used my phone (Galaxy S7 Edge) as a Hotspot and I was getting close to 60 Mbps Down and 20 Mbps Up which is a very decent upgrade from my fixed line (9Mbps/0.5 Mbps) Happy

I purchased 2 different 4G Routers for a more permanent solution:

- Asus 4G-AC55U
- Huawei B315s-22

Both are very current devices with good configuration options.

After configuring both routers and testing them to death I don't understand why both routers only manage to get half the speed of the android hotspot. I tried changing the APN, different networks etc. etc. nothing seems to help. I know my way around home networks but I can't seem to be able to fix this problem

What's really weird is that when using the router I will for example get half of the speed for downloads from different high speed servers and as opposed to the hotspot but when streaming a youtube 4k video the routers will preload the video at the same speed of the hotspot (60 Mbps)

The same for google Playstore. When I download a big game with my phone using the Internal 4G connection i get 60Mbps download speeds. Also when I Tether with my Android 4G --> Wifi --> PC I get the same 60Mbps.

As soon as I use the router it hovers around 10 Mbps at most but when I preview the Video for the game in the playstore using the same router that downloads at 10 Mbps it will preload the video at the full 60 Mbps. I don't get it.

How can I achieve the same speed of my android hotspot?
The Routers seem to be able to deliver the speed but only for certain websites/sources while the same 4G connection on the phone will bring the full speed.

I am inclined to use my old S6 as a "router" for my entire home network because of the speeds I get but it's not a viable solution for many reasons (setting up multiple PCs, Wifi Signal strengh etc.)

This is very frustrating and I would appreciate your input.

Thanks for your Ideas!

Sorry but I'm not there to check on things.

You may want to test if the DNS is dogging your testing. Pick one DNS such as a Google DNS (8.8.8.Cool to keep results pretty tuned to one or other areas.

Some cellular hotspots have single core CPUs so they work on one thing at a time. Why this matters is your usually Android phone has 2 or more cores and can multitask like a mad person.

The 10 megabits sounds odd. Almost as if the device or ISP is limiting the rate. I can't know if they did but 10 megabit is plenty for HD video so a smart cellular ISP might do that. Your Android phone won't implement that.

Sorry, from the States

I know here in the States, when the cellular companies offer unlimited data they will throttle you speeds after you have used a certain amount of data. So at the beginning of a billing period you'll get top speeds, then once you hit that amount they give you the rest of the data is slower but still unlimited. So I would make sure that's not the case there. Like the other poster said could be processing abilities of phone Vs the hotspots. I hope this helps, or you find your issue. I'd call the company to see if it's normal for your hotspots or/and check on throttling.
