hello,

Sorry for my very bad english, I am from france...

I have a mikrotik router, his name is rb751u 2nhd. with my local network, I can’t download files more than about 2Mb/s. I’d like to know if it is normal for this router, or if i can do something to make it better.
Thanks for your help.

No. It is much more for sure. But you can have queuing or very hard firewall settings that could limit the throughput. Observe tools profile what occupies cpu when downloading.

thank you for your answer. can you explain what is "queuing" ? i did not tell you , but i try to download with my samsung galaxy tab. i don’t know if there is a firewall on it... i don’t think so. do you mean a firewall on the router ? how can i observe tool profile ?

thank you

hi.

i have tryed to switch off all the firewall on the router and on my pc... always the same : 2,14 Mb/s on my galaxy tab4... i don't understand the problem... if there is a problem... on winbox i can read on wireless table Tx = 20 Mbs... maybe something is wrong with my router configuration ?
thanks for help.

The very first question is: what kind of ISP connection are you connected to ? Is it more than 2Mb/xxMb ?
If not then you have the answer as it does not matter what is the LAN-side speed as you are limited by your ISP.

"Queuing" (see the QUEUES tab) is the mechanism to shape your connections: http://wiki.mikrotik.com/wiki/Manual:Queue

That could be the reason. Also you maybe set wifi settings in wrong way. Or your tablet is not able to process faster download. Hard to say. Paste here your configuration export and provide values from wireless registration tab when downloading at maximum. And also look at could utilisation at that time. Provide clients ccq measured at router. If you don't understand terms, read manual first.

2MB/s can be normal for G standard on RB751U-2hnd. I have the same transfers on my tab. I work in a noisy enviroment, maybe you do to.

It's not normal.

In a noisy enviroment i said and YES it is normal for those circumstances!

check your internet speed with something else e.g another AP (not from MT) and see weather there is difference or not.

Ugh. Keema, you should be radiating if you live in such electromagnetically polluted environment. There are most things I have never seen but I admit, there can be circumstances that prevent higher throughput. Fortunately I have not personally experienced them and I am glad for it.
Even though this is not normal.
