Need help configuring home network

Hello,

This is a thread requesting help setting up my home network, looking for optimal settings about how I should be doing this.

I know enough about computers and networking to have made a career out of it. I am surrounded by such technology both in my workplace as my primary reason for employment, and at home where I am on the internet constantly, have built PCs for myself and friends, and maintain our home network, etcetera...

Until recently, I thought I knew enough about home networking to get me through the day and to explore the web on our own stable home network without issues. But I have been having issues recently. I have sporadic drops of internet connection (plenty of wireless signal strength, just no internet connection on some devices for a bit, then it may come back for a bit, it may not)

My setup:

Cisco DPC3825 Rogers Modem/Wireless router
Asus RT-AC87U wireless router (because the range and speeds on the Cisco modem are laughable)
Dozens of wireless devices connected to the network throughout the house

What I want to achieve:

Cisco modem (that I absolutely despise but have to have because of Rogers) takes our cable connection from the wall, and passes the internet on to the Asus router whereby every single device will connect to the Asus router either wirelessly or wired. I currently have the Asus router in a prime location to provide 5/5 bars to every corner of the house.

The difficulties I'm having:

Some items drop internet connection (note they drop internet connection, not wireless connection to the Asus router), such as my Mom's iPad (wireless), my laptop (wireless), rarely my cell phone (wireless). Other items maintain a solid connection and have rarely failed me, but if they have, so did everything else in the house. My laptop will have NO internet connection about 95% of the time lately. The iPad is tough to test because it doesn't get used often enough, but it seems when it does get used, it will be about a 50/50 whether or not it has an internet connection. Again, it's worth noting that the wireless signal is always fine, it's the internet connection itself that's the issue.

Assuming I'm setting both my Cisco modem/router, and my Asus Router back to factory settings, what settings will I be looking for when setting up to ensure proper stability in my home network? I've tried setting my modem to bridge mode, which says in the manual that when in bridge mode it will only allow connectivity through the first port. During this time I have the Asus router connected to that port.

I'm so lost, I don't understand why my internet connection is so unstable on some devices and fine on others. As I'm typing this my laptop just refreshed and regained access, but has now disconnected again.

TL;DR: What settings am I looking for when trying to properly set up my cable modem/router combo to allow my third party router to handle all traffic and connections of any sort?

I'll add and provide as much details as are necessary. I really need help on this.

That is why I asked about the wired connection. Asus is real good with their system logging. What does the router log say when the...


The Asus router is broadcasting the 2.4GHz and the 5GHz band. Each band has a different SSID for me to tell them apart. One or two devices use the 5GHz band, for maximum speed because they are close-by, and most other devices use the 2.4GHz band because the range is superior.
 


There is only one wired connection, it will only drop when everything else drops, which I believe indicates the fault of the modem.

It's also worth mentioning that I have tried 6 different wireless routers with varying firmware revisions throughout the span of a week, all with similar results. I tried 3 different D-Link Dir-880Ls, two Asus RT-AC68Us, and now finally I'm sticking with the Asus RT-AC87U. And I say similar results, because one of the D-Links was defective out of the box and made things even more difficult for a stretch.

I do believe I've gotten the fix I was looking for, over on the Rogers forums. Thank you for your help, I'm sorry to have wasted anyone's time.

The fix, by the way, has been enabling bridge mode on the modem. I was well aware of bridge mode and had tried it before, however the official tutorial on Rogers's website on how to enable bridge mode, doesn't mention a step that it almost necessary.
