I work at an e-commerce based business in a 16k warehouse. The only available ISP solution is AT&T, with each 6Mb/1.5Mb line costing $50 and fiber optic being an option for $800/mo at 20Mb/20Mb.
Around 15 clients are wired throughout the offices, and another 10 or so exist wirelessly.
I know very little about the stack as it was setup before I arrived, but I am very aware of the real problem we have: it's slow. I don't know if it is download (SpeedTest shows 18Mb down), upload (I was told you can only combine download speeds, not uploading speeds, so SpeedTest shows 1.5Mb) or latency (SpeedTest does not show anything abnormal).
We are using a PepLink to load balance the 3 lines into one solution, but I fear it may be set up incorrectly. I don't know how else to explain why the lag that exists is randomly occurring.
What are common solutions here?
