Currently using windows XP, I should have everything up to date on software.

I might try new cables, because someone pulled/ hit the cables on the ground too hard last time. like fall off because stepping on it :S

 

Everytime, i use speedtest.net application, those message constantly pop up and interrupt speed test process like " slow down and lower the speed "

Also after i reboot my router, i got the message pop up like 5-6 times, until my internet connected

 

Any thought or idea ? thanks

I assume those logs are from the router itself?

 

You could try replacing the phone cable and also try the usual isolation test (unplug EVERYTHING from EVERY phone outlet except the router - including phones, filters, alarm systems, foxtel boxes - everything) to see if that makes a difference.

 

What are the receive level and SNR figures reported by the router?

 

Did the problem occur before you did the firmware upgrade?

 

Have you had significant levels of rain recently?

 

The ADSL connection appears to be dropping out intermittently and is also syncing with inconsistent speeds.

Yes, i dont have everything plugged except the router itself. I never had the problem before when im using old version firmware, i tried to restore backup system and apparently it doesnt roll back firmware version

I dont think there is rain in my area recently. But i do have alot trouble with my ISP like in Past 6 month, always having dropping issue and have to call Internode to fix the line, etc. Should i ask them again if problem were coming from them ?

 

Another thing, I switched cables between computer, well those message doesnt pop up as much like before, but still happen sometimes. I might try to get new cables tomorrow, since its really old

It's likely that either the 'network cable is unplugged' message is a separate problem from the ADSL dropouts or the router is shagged and you need to manually try to find the old firmware version and reinstall that as it's causing stability issues.

 

You should still try replacing the cabled between the router and the phone socket however.

Called internode last night, They told me to change setting PPP-OA into PPP-E on router. And i just replace my old cable with new one. Problem still there :(

 

Any idea where i can find old version firmware for dynalink ?

After the firmware update did you do a reset to factory defaults on the modem, then a modem reboot? If not do that first as this should always be done after a firmware update.

Also did you get the right country one? Australia has AU_firmware in the file name and NZ has NZ_Firmware in the file name.

Yea apparently it wasnt Firmware issue. It was the caps blown over 3yrs old.

I bought new router, everything seems ok.

Ah the aging capacitor problem. If you still have the old Dynalink you could try removing the bulging and leaking capacitors and soldering in new ones to give you a spare router.

A fidddly job but possible to do, I have resurrected 2 mainboards and three LCD monitors by doing this.

Swap the cable.

Swap the network card.

Make sure your PC is not uploading/downloading over capacity.

 

 

If all those don't help, time for a new router.
