Hi There
I am using mikrotik on x86
is it advisable to always reboot it every 24 hours ? or never?

Alex

Unless you're experiencing some trouble with it, you don't need to reboot it, ever.

Thz for you reply dear boen_robot
this is because some time, my ping Start showing time out.then if any download is on,it will keep downloaded. but you can't open pages anymore.
Then wen i reboot the Mikrotik or the ADSL modem, it will came normal for some Short time then start back after.

What can be the problem?

does this happen only when you're downloading? do you have any queue in place? also, are those reply times always that high? or only when you're downloading?

Hi Devil!
This can happen at any time downloading or not. I have no Queue . This is our normal reply time

You might wanna contact the support then. This is not a normal behavior at all.

Hi there!

can this be caused by the firewall Mikrotik?
The ADSL Modem?
the Switch?
Cables?
I am confused!
please someone Help.

it could be caused by some firewall rules, but not the default ones. you had to create some very specific rules that could result in such behavior. it also could be your adsl modem, your switch, your cable, your isp,... which is why its important to narrow it down. i suggest to connect your adsl modem cable to your computer directly and see if this happens again. if it did, that would mean the problem is somewhere else.

Hi Devil!
So i should do that at the precise time when this is happening.
But some time, it work great.
can the firewall work just some time?
but not always at the same time

next time it happened, use tracert command in windows. for google.com , facebook.com and 195.24.213.129: run each command couple of times and post the result. you can only include part of the ip addresses in the result (like 192.168.xxx.xxx) if you are concern about your privacy. this could hopefully help to find out whats wrong

here are the first results

This is when the Connection is the best

Alright, thanks for including both tracert results for when the connection is ok and when its not. i'm going to guess 192.168.1.1, is your routeros ip address and anything after that point, is your isp. including 10.70.70.1 and 195.24.213.129. if my assumptions are wrong, please correct me.

As you can see, something really fishy is going on. when your traffic is routed through 10.70.70.1 , your connection is fine but when it goes through 195.24.213.129 , your problem starts to appear(please make sure that its really the case. try it couple of more times when your connection is fine and when its not to see if it stays like this). first question that comes in mind is that why does it take two different routes. i'm not quite familiar with routing protocols but are you using any?

you said you're using adsl. my guess is you have bridged that to your router and you router is connecting through pppoe or something, is that right? do you experience a lot disconnections?

for the next step, do the following:
tracert 10.70.70.1 , when you experience those ping timeouts again. do it couple of times and post the result.
post '/ip route print detail' for both when your connection is ok and when its not.

Unless you are using multiple links in your router or using some sort of routing protocol that i have no idea how they work, i think at this point, its safe to say, the problem is your isp. but there is a slight chance that you could fix it by adding a static route.
Please take your time and answer to all the questions

Many thanks for your disposal and your support

192.168.1.1 is my ADSL modem
172.16.1.1 is my RouterOS

first question that comes in mind is that why does it take two different routes. i'm not quite familiar with routing protocols but are you using any?
I have no idea.
I am using one single ADSL line to run my hotspot.

you said you're using adsl. my guess is you have bridged that to your router and you router is connecting through pppoe or something, is that right?
for Sure
cuz my ADSL can work when i connect in bridge or in PPPOE

do you experience a lot disconnections?
If i launch a download, when the problem start, the download wl continous in the normal speed or even it affect it,it wl not be visible.

I am using just one link in my Router

Alright, thanks for including both tracert results for when the connection is ok and when its not. i'm going to guess 192.168.1.1, is your routeros ip address and anything after that point, is your isp. including 10.70.70.1 and 195.24.213.129. if my assumptions are wrong, please correct me.

I have this scenario
ISP - ADSL modem - Mikrotik - Switch - PCs,AP
no PC is directly connected to the modem. even mine is connected to the Switch

Alright, so i think at this point, its safe to say its either your adsl modem or your isp. the latter seems more likely. unfortunately, because of your setup, you have to diagnose the problem in your adsl modem now. cause that's the point where things go wrong. have you set any static route in your adsl modem? what is that '195.24.213.129' address? see if you can override the default route in your adsl modem by adding a static route with destination of 0.0.0.0/0 and gateway of 10.70.70.1. i suspect the reason why you can still get full speed download even when the problem occurs, is that because of how tcp protocol works. if your pc fails to get a packet, the host can resend it.
Almost all adsl modems that I've seen are designed for home usage. they lack a lot of settings and even some settings that they do have, sometimes don't work correctly. that's why i don't like the idea of an adsl modem, routing the traffic directly. again, in almost all adsl modems, there is an option for bridging mode (instead of routing mode). if you setup your adsl modem as a bridge, then you are able to directly connect to your isp through the routeros (usually via pppoe). then not only you can diagnose the problem way easier, but you can setup more advanced settings for your wan connection in routeros as well.

I hope that it is the modem who is bad!
I buy a new adsl modem which I have attached a fan. [D-link DSL-254OU]
up to now, it seem to be working fine.
do you have any ideas about the "Cisco 837-K9-64 ADSL Router 64MB Cisco837 K9" if it can be a good ADSL modem, or any other one to propose to me.

unfortunately, i do not work with adsl modems a lot. so i can't recommend any.

see if that new modem solves your problem, but just remember, there is a quite good chance that it doesn't. your traffic was taking a different route, this is not something that could be caused by some malfunction. if it happened again, contact your isp and include those tracert results, they should be able to instantly identify the problem.

tu as raison mon frere!
The problem just start again with the new modem.
wen the Default Gateway is : 195.24.213.129
but,
wen the Default Gateway is : 10.70.70.1, the connection is gud.

I will get back to you after contacting my ISP.

Hi Dear!
my isp is not doing anything since last time.
please, it there any way to fix this problem from my site?
like forcing the traffic to pass tru the 10.70.70.1
he said it is same router that is having many address pools.

Hello Dear!
my isp is not doing anything to help me.
can you please help me to fix this problem from my site?
a possibility to force the traffic to pass through the 10.70.70.1

Hi There

ALex,

We have the same problem.
We also need to reboot every 24 hours.

hi
it is may be happen for your internet banthwith.
if your internet bandwith is full,then your ping time is timeout.

This happen even when less than 10% is used

hi
it is may be happen for your internet banthwith.
if your internet bandwith is full,then your ping time is timeout.

We have a good fiber (direct) inter connect with plenty spare capacity. Far more than we can use.
Our band width is not the problem. In our case the wireless cardss seem to looase response on the 386 if you then reboot all is 100%

Somethimes I also have something like you ... and I discover that is problem in swich ... my 3-com gigabit swich sometime need to be reboot
When this hapening try to turn of - on swich

I have a auto reboot on the system to reboot the 386 every X hours that works ok.
It is a pity of this.

What would still be a 1000% improvement is a hardware dead man timer toggled by the software ( for reset) .

We find under certain issues when the router hangs it must be physically rebooted.
If mtik would have added this dead man timer in the software I can assure you the system would be in a different class.
