Hello, I have searched the forum but hits for this general a question have not proved successful.
My company is moving from a 10MB Fiberoptic internet connection to a 100MB connection. Our production Mikrotik is a RB1100AH. I am testing the configuration and connectivity using our former (now backup) Mikrotik router, an RB532A.
With the production config on the RB532A running ROS 6.28, a simple velocity test using www.speedtest.net returns an average download speed of 43.88MB. When I connect a laptop to the new 100MB connection without going thru the Mikrotik, the download speed is 95+MB.
I reset the RB532A to defaults, and used a simple setup configuration - Eth1 LAN&DHCP, Eth3 WAN/ISP, single masguerade rule in NAT. and the avg download speed increased to 52.19MB. I DID see that CPU usage on the RB532A was pegged at 100% once the download test started.
Unfortunately, I have not yet tried a test from the RB1100AH as this is our primary/production router and so changes are not easily made on the device. The RB1100AH is running ROS 6.25.
Is it probable that the RB532A can’t handle the 100MB connection? Or is there some basic configuration I am missing?
No it cant handle that. It has 400 mhz CPU and in my opinion, its way too weak. I have couple of 750s and they struggle between 20-25 megs, no added firewall/nat rules, just plain tcp bw test… 1100 is different story.
I was hoping it would just be a matter of the RB532A not being able to handle the full bandwidth. The CPU pegged at 100% with no FW filter rules and no real NAT going on pointed me there, but it’s good to have some confirmation.
Regarding the production Mikrotik. We are running the RB1100AH and NOT the RB1100AHx2 (Dual Core Processor).
So if I understand you all correctly, it should be able to handle the 100MB connection with active Firewall Filter rules, NAT, Layer 7 protocols, etc and still keep us a lot closer to our full bandwidth. Correct?
As a side note: the MicroSD card, this RB has had history of not maintaining the the MicroSD available in “Disks” after a reboot. Only a Shutdown and then restart makes the SD available. Is this still troublesome for people? The MicroSD is a class6.
FYI to everyone:
Was able to configure 100MB connection using two other ports (LAN/WAN) and speed test from speedtest.net with Router running both connections and FW Filters, Nat etc returned +/- 90-95MB download and upload speeds with CPU usage at 30-40%. Thanks again for the replies.
