I’ve been plagued with this problem for a while with a few devices and with some info from this thread I think I’ve resolved by removing always-broadcast=“yes” from my static dhcp assignments after trying everything under the sun including removing STP/RSTP from my bridge with VLANs configured, etc.
It seems that at some point I had the always-broadcast=“yes” checked off as a default or the defaults changed on the discovered DHCP items before I made them static or I turned on this always-broadcast=“yes” at some point.
I thought at first it was Apple specific devices like my Mac book pro, iPad, iPhones, etc but when I encountered this yet again in the last week in my logs I googled and dug deeper and put 2 and 2 together after I decided to do a /export and saw all these always-broadcast=“yes” references and one person mentioning when converting via make-static that these issues showed up I didn’t have this checked off when I looked at the dhcp server setup but when I saw on the static leases I started to correlate
Hope this helps someone that comes across this after the pain I went through to get to this point
Now if Mikrotik could just make a router like the RB4011 that could support SFP GPON and SFP+ GPON at 1Gbps / 2.5Gbps / 5.0Gbps / 10Gbps and 40Gbps (LOL.
) then I would be able to sync at 2.5Gbps or 5Gbps for our Bell Fibe service here in Canada to get full bandwidth since my ISP goes to 1.5Gbps currently and the 1Gbps service regularly goes up to 1.1/1.2Gbps so leaving this on the floor. People are using 1Gbps SFP media converters which they can get approx 940/940 Mbps but some can only get 750-800. Alas my hEX RB750GR3 does seem powerful enough to get above 650-700Mbps either way with download slower because of sync speed apparently so 550-600.
I am hunting for a router to replace the hEX RB750GR3 and the RB4011 would be ideal as it can do up to 75% line speed of 10Gbps SFP with bridging/routing/firewall rules which would be more than I can foresee needing (7.5Gbps connection to home!
) at this time but alas no SFP GPON support and not clear if SFP+ GPON are supported if ISP changes to SFP+ GPON later this year. The CRS3xx series don’t seem powerful enough to route / bridge / filter any more than my hEX RB750GR3 as switches really should do this and I already have some TP Link smart switches that are adequate for this until I upgrade to 10G switches later but can do LAG for now
Alas my work on fixing the “DHCP offering lease without success” issue may go to waste if I can’t get a new router than keep up with multi gigabit internet via SFP/SFP+ GPON at 1/2.5/5/10/40Gbps sync as may have to look at new Ubiquiti solutions just as I was getting used to RouterOS and its flexibility. Alternatively may have to look at pfSense or Linux solutions which I believe RouterOS is based on
Come one Mikrotik looking for a solution especially since RB2011 apparently can see these SFP GPONs just not at 2.5Gbps but rather 1/1.25Gbps
