Hi

i have experienced a weird issue here is that Internet Speed drops on ADSL port(WAN1), however, it shows better internet speed on WAN2 port. Just to let u know that I used same ADSL connection for testing on both ports one by one separately.

Can anyone elaborate is this normal or there are some kind of configurations on ADSL ports causing normal internet speed dropping.

Thanks

what model or firmware?

My 2860 drops WAN 1 all the time, latest firmware
Model Name Vigor2860n+ System Up Time 2:8:10
Router Name cc Current Time 2014 May 9 Fri 17:47:50
Firmware Version 3.7.4.1 Build Date/Time Mar 20 2014 14:09:50
DSL Version 544401_A

I have not asked why yet, to busy trying to resolve a AP-900 issue

Some has changed backwards firmware (using the *rst* file) and the issue sloved

Some disabled QoS tagging & worked

also maybe if you change modem code could help ... WAN >> General Setup>wan 1> DSL Modem Code

There is also a newer beta 3.7.5 if you want to try
