I have the same slow speed using Balance 210.
I have 4 Grandfathered Verizon Unlimited accounts and I am one mile line-of-sight from the tower.
SIM1 - Cradlepoint Router
SIM2 - Verizon 8800L Hotspot
SIM 3 - Verizon 8800L Hotspot
SIM 4 - Verizon 7700 Hotspot
I can connect to each of those individually and get 60-90+ Mbs.
When SpeedFusion is turned on, I get maybe 50up/20down. I know it’s setup right since a Peplink expert on here set it up for me.
If SpeedFusion is off, then the router can provide a max 180~ down when I do a Google Fiber speed test.
In my case, SpeedFusion hasn’t been anything like what I expected it to be. The main reason I use it is for consistency. But I prefer to be consistently fast instead of consistently slow.
I also use Vultr. Any chance the problem is with them?
