Hello,
We have CCR-1036 deployed as NAS. Users are getting proper speed on speedtest.net as per their subscribed plan but speed sucks while downloading any file from internet. This is intermittent issue. Sometime they get good speed but sometime it drops down to KB.
Latency to gateway (NAS) is normal from user endpoint. Default MTU set in CCR. CPU of CCR is around 20%. No issue in physical connectivity.
Please help.
You provide a bit to less info to say whats wrong.. How is CPU? do you use nat? Do you have fragmentation of packet? do the btest use udp or tcp? etc. You will need to provide more information to have an correct answer.
Hi,
CPU is normal (around 20%).
Doing NAT with 1:4 (public:private). Before authentication private IP through DHCP server running on CCR. After authentication private IP allocated from pool which is further NATing with public IP in CCR.
MTU is default 1500 on CCR.
Queue on CCR around 1500.
Both PPPoE and HTTP login.
WAN interface BW during peak is about 600 Mbit.
Waiting for response from Mikrotik Support.
Thanks
Any ideas ? Anyone ?
Do I understand correctly your initial post that you have some USB disks connected to CCR and that users connect to that CCR file sharing services? It had been mentioned in few posts around this forum that MTs are not quite fast for this kind of usage and that these services exist on MT more to aid administration.
Both PPPoE and HTTP login.
It seems like a mtu issue… run 1480 as mtu at pppoe interface. its like if you send a 1500 byte packet in tcp - it would be fragmented into 2 packages. if you maximum is let say 1000 packet per second, you reduce to 500 per sec when fragmenting into 2 packages. try to do a udp test. then result should be better.
To the other ansver - no NAS is like network access server. nor NAS like disk server. a pppoe server is often called a NAS
