Did a speedtest on LAN and indeed it's 300mbps! But stock ZTE cannot go, max only 50mbps..planning to change to an AC wless router, any recommendations? Thinking of the Asus RT-AC68U..Or should I also change the modem?

Yes bro, I just purchased a DLink DIR-868L to replace the ZTE router..I kept the ONU which is the modem intact..but wireless speeds max so far is 80++mbps @ 5GHz, not sure how I can maximise the full speed..if can't, better downgrade to 100mbps line coz can't fully utilize the 300mbps right?

You need an 802.11ac wireless router in order to enjoy the full speed that you have been upgraded to. That's what I did..but bear in mind that some older computer systems/phones/tablets don't have a compatible 802.11ac receiver so you might need to purchase one or run at a lower frequency speed

Oh sorry my bad, that's the Huawei modem dialer, not the wireless router, which I meant earlier. I am not sure about this as my current Huawei is able to handle the speed. Hopefully others can help you out here.

Thanks for the feedback bro. I did sit next to the router and get around 120++Mbps download speed on wifi with a AC7260 wireless card as shown below. Any thoughts on how to increase it to reflect 300Mbps?

I am using dlink 868 connected to wifi a/c dualband 7250 @ 300mbps package but max only around 120mbps via wifi..I am kinda sure the dlink 850 won't get 300mbps via wifi...

Bro, there's nothing much to change right? Just PPPoE username/pword and wifi dual band setup only right? Please share what changes that you did from your end ya,, thanks
