Hi there,
Happy d-link user here, however I'm having issues with the dir-615 router.
Firstly - I have had a DIR-655 for years, and this is a treat - channeling everything from IPTV, to a fast fiber connection, transfers - no sweats.
Then I had to setup a router for a friend, and recommended the DIR-615.
Setup the router, and max it would connect with was 150mb - I changed the settings accordingly:
auto channel scan
channel width: auto 20/40mhz
So this "opened" up the 300mb speed - however only for 5 mins, then it falls down to 150mb.
My laptop (lenovo) connects to the dir-655 just fine at full speed, and this is also the machine I used for testing the dir-615.
It's ax Hx firmware, FW: 8.04
What I can conclude by using inssider, and xirrus wifi inspector is that it generates 2 channels - and then after 5mins of connectivity looses a channel, and then the speed drops.
I got a new router from the dealer, same issue. Then a friend of mine lent me an ancient dir-615, and interestingly enough this had the same configuration option of "Transmission rate" in the wireless settings page! Just like the dir-655.
and also connects at 300mb...
This option is missing from the 615, please advise :-)
any ideas?
