Stability of accessing my network through ddns

Hi ,

I have a usb modem ( dongle with a simcard ) connected to my router through USB , and inside my network i've a microcontroller act as a actualweb server with a static private ip .

What i want is to access this webserver through internet (from outside my network ) , and i'm done with ddns service and i've entered the right information in the DDNS field , also done with port forwarding ( port 80 ) ,

My problem that when i try to access that server , the matter became not stable , or in another word , some times i can access it and somtimes not , even if i try to reach it directly through my public ip ( not through the ddns ) .

Further more , even id i try it and it became success , the connection is done through some devices and not through others , also for the internet service provider , if i try to access it using a network connected to the same isp i'm connected to , i success , but at the same time when i try it with a device connected to a different isp , it fails !!!

What the wrong withmy network ?!

That sounds like a problem relating to your ISP's connectivity - particularly if you're also having problems when using your WAN IP.

There may not be much you can do other than changing your ISP.

Why is that ?!

You're comparing apples with oranges - there is no way for us to know why your mobile network connection is faster than ADSL. Both of those are influenced by where you are (and what providers you are using). If I had to guess I'd say you're right on the edge of ADSL coverage from your telephone exchange but well placed for the mobile provider you are using.

You might find that a different mobile provider is more stable and performs as well as your current provider. You may also find that you already have the best of them.

I mean is there any relation between changing the ISP ( with almost same downloading speed ) with the ddns , or port forwarding ?!

Other than having to wait for the update client to update your hostname, no.

Hi ,

No not that , the slow speed doesn't related to the ISPs , the i ternet speed is within 2 MB , and even when you try to download any thing , the speed is not that bad , no at all , it is good , but downloading that page from the server is too slow ,

Hi ,

Yeah , Thats right , there is a problem for sure from ISP side , that what i'm thinking of , thats why i've tried this matter with another ISP ( with adsl connection ) , And i can access the server but the speed of downloading that page was incridible ,, it was too slow , and the page is not fully downloaded , some design component ( color , pictures ) is missing , !!!

Why is that ?!
