I am new to Mikrotik; not newer to the world of networking though. I recently installed RB2011il-IN Router at my house with all default out of the box settings. I have Time Warner Cable with 300Mbps/30Mbps using SB6183 modem.
When I connect my laptop directly to the modem and run speedtest; I get 300Mbps+ speeds. When I connect via my RB2011il-IN Mikrotik Router using the ether1 port (default); I get upto 95Mbps down and 25Mbps up.
To begin with, I reset my router back to factory default settings and made sure the firmware was up to date; still the same speed. I haven't done anything else yet; I wanted to know if anyone had a similar experience like mine and what was the outcome; was it bad piece of hardware or changing the WAN port from ether1 to another port fixed it?
I read some posts on the web that there are some Mikrotik users who faced this problem and couple of them had to replace their routers to another brand in general. I will really appreciate the feedback from anyone and everyone that can help suggest some ideas to try out; I really like options in this router and would like to give it a fair chance and not dump it for another brand.

Re: Time Warner Cable - SB6183 - RB2011il-IN - 300Mbps - Slow WAN speed
Which port do you use for the LAN?
How did you test the speed?

I have tried Port 5 (Gigabit Ethernet) and then Port 6 and Port 7 (Fast Ethernet). I use http://www.speedtest.net and http://www.speakeasy.net/speedtestWhich port do you use for the LAN?

Re:
That's exactly how I have it set. Ether1 is for WAN; Ether2 to 5 has my laptops plugged-in. The RB2011il-IN doesn't have a gigabit link light. The LED's on the front represent port numbers. The profiler showed bridge, ethernet and firewall activity when I ran a speed test.Use ether1 as wan and ether2-5 as lan. Check the port status if it negotiated gigabit link. Check the fasttrack is on. See the profiler while making the test. What does it say?
After I got home today; I also did a hard reset and cleared all the settings. Connected my Time Warner Cable on ether1 and ether2 had my laptop; and still the same.

Re: Time Warner Cable - SB6183 - RB2011il-IN - 300Mbps - Slow WAN speed
I am having the same problem with Cox Cable. I have a SB6182 modem connected to a RB750GL. The circuit is provisioned for 25mb down and 5mb up, which I get connected directly to the modem. I have a /28 block and the RB750 is connected between the modem and the primary router strictly for routing of the IP addresses. It has a very basic configuration, and shows gigabit links between devices. With the RB750 in the mix, the download drops to 6mb and the upload stays at 5mb. I also test using Speakeasy and Speedtest.net. It is running version 6.35.1.
Any suggestions would be appreciated.

I was able to solve my problem with slow speeds. I don't know what causes it, but I have read in a few places that it seems to happen with Routerboards and Arris cable modems.
I solved my problem by replacing the Routerboard 750GL with a new router from Ubiquity (an Edgerouter X). The specs are similar to the 750GL, just with a faster CPU. https://www.ubnt.com/edgemax/edgerouter-x/
I duplicated the configuration, cloned the MAC address to the WAN port, and swapped the devices. Down time was only a couple minutes, and I didn't have to reboot the modem or any other devices. Speeds were immediately back to where they should be.

Thanks guys, I had the same issue with an Arris 6183 on TWC with 300Mbps down connection. I followed the rules at http://wiki.mikrotik.com/wiki/Manual:Wiki/Fasttrack and now the speed tests come close to 300Mbps.
