Dhcp broken and bandwitch restricted

[santa78]

Hello,
A few months ago I had created a topic for my dhcp problem on my XR700 which stopped working randomly.

Frazer provided me with firmware V1.0.1.24 which should resolve this problem.

The problem is back, plus I unfortunately now have another even more problematic problem ...

I am in 1gigabit fiber, my speed is randomly restricted by my netduma router to 100mbits without me modifying the configuration.
This causes me a lot of problem, it is not just one device but ALL that are restricted.

Having several servers at home, consoles, workstation, ip tv etc. this causes me a real problem in my work because the only way to solve this problem (and that of the dhcp) is to restart the router.

Can you help me solve these problems?
Should I send you logs?

Sorry to hear you're having these issues. Could you provide the following information please?

• What is your exact physical setup?
• What does it say for lease obtained/expires in Settings > Monitoring > Connection Status?
• In Device Manager, switch to table view - on the ports what does the link speed say for each?
• What category of ethernet cables are you using?
• Do WiFi speeds also suffer the same slow speeds?

Hi @Netduma Fraser 

 

1 - Fiber Orange => Routeur XR700 (in dmz/ip fixe) connected with a cat6 cable

Firmware : V1.0.1.24

2 - Actually this but i have reboot yesterday my router because the network have the problem (restricted 100mbits)

3 - this :

4 - I use a cat6 ethernet cable and sfp+
5 - I haven't checked yet because I mainly use wired, I can try the next bug...

 

[Netduma Fraser]

Okay that's great thank you, so doesn't seem to be limited by the cables at all. On the QoS page in the Anti-Bufferbloat 3 line menu option could you disable QoS completely there and then try a wired speed test and see what you get please?

[santa78]

@Netduma Fraser if i test a speedtest the bandwitch is good, but if i test a bandwitch after the bug isnt working (restricted to 90/100mbits)

If you want i can test to disable qos when the bug appears to see if it fixes the problem?
 

[Netduma Fraser]

So there are times when you receive your full speeds and times when it randomly drops? If so yes please disable QoS fully when the speed appears to drop and see if you can then get full speeds.

[santa78]

Excactly, ok i try this solution after the problem back

[santa78]

The problem back again, i have try disable the QOS but the problem is still there

 

[Netduma Fraser]

What is the speedtest you're using? If you use Speedtest.net do you get the same results?

[santa78]

I have use the google test, but i have try with speedtest.net and its same

After reboot my speedtest have the good result (~900mbits)

[Netduma Fraser]

Just to check, when this happens does the ISP modem/router report full speeds? Are you able to put the ISP router in modem or bridge mode?

[santa78]

@Netduma Fraser i dont have try but if the reboot of the netduma router fix the problem I think that the problem does not come from the box of my ISP

But if you want i can try.

Im not sure, for the modem/bridge mode, i have the Orange box (France), actually my Orange routeur have the DHCP disable, the IP of my XR700 fixed, the XR700 is in DMZ.

 

[Netduma Fraser]

Yes please do just in case, it might be the ISP router drops the speeds momentarily and the router is unable to properly re-establish the speeds. What is the model of the Orange box?

[santa78]

Livebox v4

[Netduma Fraser]

Thanks, no bridge mode unfortunately. Are ALL devices connected to the XR or are some connected to the livebox?

[santa78]

Only connected to the XR700

[Netduma Fraser]

Could you try reinstalling the firmware using TFTP please and then doing a reset and see if the issue returns?

[santa78]

i go to the vacation tomorrow, i try in 10 days

 

[santa78]

for information i have a switch MikroTik CRS309-1G-8S+IN connect to the SFP+ port on my XR700.

Its for my 2 nas and my esxi server, I don't know if it can be linked to the problem

[Netduma Fraser]

On the interface have you switched it to use that port for WAN? It may be a good idea to try without it in case that is the cause. 

[santa78]

yes in my config the sfp+ is configured on WAN

[Netduma Fraser]

Okay thanks, if you remove that and switch it back to use the normal WAN port let us know if you reach your speeds correctly then.

[santa78]

If i disable the option the sfp+ port is disabled ?

its compliclated for me to migrate all my nas/server linked to my SFP+ Switch on ethernet  

 

(For information on my sfp+ switch the MTU is configured to 9000, but on my netduma i dont have change MTU parameter)

[Netduma Fraser]

Yes, could you just disable for a short period - no need to move anything around but disable and use the normal WAN port and see if you get expected speeds?
