Title: Router keeps crashing
Post by: MariusBogdan on January 18, 2019, 05:31:11 AM
Hello guys , im pretty new to this forum . My name is Marius and im from Romania . In the past i have used a dlink router ( cant remember the model now ) , but it was something AC1200 and had 4 antenas like this one and it worked fine for a time ( 2 years or so ) but its range was kinda modest . I never did anything to the settings to the old AC1200 router , besides plugging it and using the little wizard to select ppoe settings and putting my info into it and then making a wifi with my name and password . Like a i said im a noob when it comes to setting the best settings for routers and so on .

Anyway i wanted to make an upgrade and to continue with the dlink brand and i decided to get the AC1900 dir 878 . all well with it when i got it , i used the little wizard but this time i made a 2.4 ghz for me and a 5 ghz for my father to use it in his room to watch netflix on his tv . But the problems for me came soon , ive realised when i was using the phone with wifi i would get small buffers and the biggest thing that turned me off from the router was the fact that when i was playing games on my PC like league of legends or rainbow six siege it would disconnect me out of nowhere , even tho in games i would have like 30 ms ping or so . then ive read on the forum that someone resolved the router crashes ( maybe there arent even crashes ) when he disabled smart connect . i tried that too , but i still get disconnected from my games .

Its very annoying cause if you disconnect from rainbow six siege , you cant log back in the same game and i have to start another and another .
Anyway if someone has any tips for me , i would gladly try to follow , as i said i got no idea how to use the settings in the router page , besides the little wizard .

Its even more frustrating that the old dlink router worked fine  but its range was s***ty.
Thanks for hearing me out .
Marius !

Internet Service Provider and Modem Configurations

I recommend that you have your ISP check the cabling going to the ISP modem, check signal levels going to the ISP modem. For DSL or Fiber service lines, ensure that the ISP is using good working phone or cable lines to the DSL modem and that the phone lines are filtered correctly. For cable Internet, RG-6 coaxial cable is needed, not RG-59. Check for t.v. line splitters and remove them as they can introduce noise on the line and lower the signal going to the ISP modem. I recommend having the ISP service physically check the lines going from the out side to the ISP modem. Connecting to the ISP modem could result in a false positive as the signal to the modem could be just enough to that point then adding on a router, could see problems. The router operation is dependent upon getting good data flow from the ISP modem and the modem is dependent upon getting good signal from the ISP Service.

Router and Wired Configurations
Some things to try: - Log into the routers web page at Use IE, Opera or FF to manage the router. Besure to log into the Admin account on the router.

Wireless Configurations

Router Placement
Forum User - "Well I feel really dumb. After moving the router away from other electronic devices my speeds are back to normal. Just a heads up for anyone experiencing slow speeds, you might want to move it away from other electronics and see if that helps."
3-6' feet minimum safe distance between devices.
Placement on main level floor and central in the building and WELL ventilated is preferred. Not in basements or closets as building materials, or near by electronics devices could interfere or hinder good signal propagation.
