I will admit from the start that I am a newb to Mikrotik. Sorry.
While my HEX and Unifi UAP-AC-Lite combo is head and above the 6 year old DLink N-300 Cloud router they replaced, I have noticed a symptom I had hoped using a Mikrotik router would have hopefully cured. I am having to reboot the HEX several times per week to keep the throughput up, or it drops to no higher than 20 Mbps regardless of time of day or current household utilization.
With a total of 12 wireless connections (3 cell phones, 2 tablets, 2 laptops, 4 Wi-fi TVs, Xbox One S, PS3), the D-LINK WOULD NEED REBOOTED SEVERAL TIMES PER WEEK in order for some devices to reconnect (One S, PS3, laptop) while other's (wi-fi TVs) would still be connected and functioning -- not even mentioning that when everything was working, lag was a semi-routine occurrence.That was back when I only had 25 Mbps internet, so the old D-Link as well as my connection speed could be scapegoated.
I upgraded to 40 Mbps connection because I wanted to drop my overpriced digital cable (no HD) for the cheaper but still higher quality of PSVue.
I did say that my internet connection is only 40 Mbps, but through multiple tests on the One S (wireless), Cell phone (wi-fi) using Speedtest, computer (1 Gb wired connection directly to HEX) using Speedtest, all regularly register between 100 to 170 Mbps.
What is odd, is that after about 3 or 4 days, the connection starts capping out at 20 Mbps (regardless of reboots to the cable modem and UAP). As soon as I reboot the HEX, and check Speedtest again, the speed is right back up to between 100 to 200 Mbps. Why is this???
I get that internet connections routinely cap-out below the advertised speed. I am not trying to be ungrateful, I just want to know WHY THE HEX SEEMS TO BE SLOWING THINGS DOWN?
