Modem drops wan connection

Post by au6usto » Fri Dec 14, 2012 4:59 pm

Hello people! I'm having wan connections problems since a few months but I still couldn't solve it.
I tried installing new phone wires in my house and the SNR and line attenuation now it's better (as far as I know).

What do you recommend me to do?
I'm still getting this on my log:

RouterTech Firmware Tool v0.97b - by TheChief : Router check 14/12/2012 12:29:48

*** WARNING! There are possible compatibility issues. This is the compatibility failure report:
  * Unknown/Unsupported core logic

Attempting to install RouterTech firmwares would probably trash your router! So do NOT do it.
But if you insist on going ahead (entirely AT YOUR OWN PERIL!), here is a further report: 
 
Select an AR7WRD 1350A PSPBOOT 4 PORT firmware.
Latest: routertech-ar7wrd-1350A-pspboot-firmware-20120130.zip
Note: a later version of the firmware may exist depending on the how up to date the Firmware Tool is.
 
Please read the instructions that come with the firmware files before you upgrade.
 
According to your current MTD values, you should be able to upgrade using a single firmware image.
 
An environment restoration script has been generated for The PC-Tool/Adam2App only.
 
Your 4-port router does not seem to have a Marvell-compatible switch.
The RouterTech firmware partly supports the RTL305SC, IP175C, and (to
a lesser extent) ADM6996M switches. But there could be problems. 

Proceed at your own risk!

Re: Modem drops wan connection

Post by mstombs » Sat Dec 15, 2012 4:26 pm

What speed service do you subscribe too? 5000/500 is heavily restricted, or if that's what the modem has negotiated down to you have a big problem with noise or basic compatibility between your modem and the ISP!

If you do only have a low speed connection it may be more robust in ADSL1 .GMT mode - which should be good for 8000/1000. ADSL1 doesn't use the high frequency bands that ADSL2_PLUS does.

You mention wiring - have you tried plugging directly into the master socket etc?

:?: if the modem is past warranty / has seen non stop service for more than a year
crack it open its the capacitors
if anyone is bulging you have your culprit else suggest to replace them all with same rating ( farads) higher voltage rating than current rating and if possible higher temperature tolerances 105 c instead of 85 c

and see if the ar7 processor has heatsink on it if not place one to cool it off :mrgreen:

I was subscribed to 7424/1023 but had the same problems that I mentioned so the ISP lowered my speed.
I had tried to use ADSL1 but got the same errors.

Oh! Unluckly here in my city we have temperatures about 40ºC in this season. Just for that I think It could be heat problem for that router as you said.
I got it 3 o 4 years ago.
Thanks for the tips! I will try it.
