Hello 
New to the forums here. A little experience with mikrotik. I am a system administrator by trade. Most comfortable with debian based distros. Networking has always been my achilles heel. I have some experience with juniper os and enterprise cisco managed switches. But routeros webfig still made my brain hurt the first hour or so. But finally got everything setup and stable for my home network. Or so I thought
Im running the CRS125-24G-1S-RM which will be the backbone of my home network
Setup is as so
Modem -> UPS -> CRS125-24G-1S-RM on ether1 -> Desktop on ether7
-> Devstack on ether11
-> Ubiquiti UniFi AP on ether18
-> Freenas on ether16
I struggled getting the dhcp server setup the way i wanted with manual configuration. And ended up using the quick set. Using the quick set i set connection type to automatic as my modem will provide dhcp to ether1 and checked bridge all LAN ports.
Everything seemed to be running great. Near 1Gb speeds from freenas to the desktop . But WAN activity was slow. I had a 105Mb down connection and was often hitting the limits of my old 10/100 router. But with this new setup im only hitting 25Mb or 3.1MBps download speeds. WHEN I have a connection on WAN. The connection seems to drop every few hours and only a restart of the modem will bring it back to life. Im not sure if there is something I have set wrong or what. When it first obtains the lease it shows its a 3 day lease. This is what I get in the logs when the connection drops with my ip edited out

Message dhcp-client on ether1 got IP address 'My IP Same As Above'
To ensure this wasnt an issue with my ISP I configured as below
Modem -> UPS -> Desktop
And was receiving roughly 125Mb download for 6+ hours with no dropped connection
Im not sure if they are 2 seperate issues or both caused by the same problem. Im either close. Or in over my head more than I thought ;( Any help would be appreciated

Speeds are slightly better. About 4MBps or 32Mbps. Still only 1/3 of what it should be. I havent had it drop the wan yet. But its only been about 10 minutes. I checked the cpu and ram usage as well. While running downloads simultaneous downloads
Free Memory 102.0 MiB
Total Memory 128.0 MiB
CPU MIPS 74Kc V4.12
CPU Count 1
CPU Frequency 600 MHz
CPU Load 37%
EDIT 2:
Strange strange. Download speeds slowly crept up to about 56Mbps or 7Mbps then hung out for an hour or so then dropped back down to 25 or 3Mbps about an hour later wan dropped again. No errors in the logs this time. dhclient showed it was still bonded. And had the correct ip. This time I let the modem assign it a lease and set it as static. Will see if that prevents the drops. But I am still limited to 25Mbps on the wan port
