I'm tried using DIR-825/842/860L as my main router.
and they all went to the same problem which causes my internet connection lost after couple of days or even hours.
Need to reboot the device the turn back everything well onlined.

So any recommend stabled routers?
I have 15 AP devices connected.
20~50 Client users (PC+MOBILE)
and some IPCamera device to port forwarding.


Will the DIR-855L or DIR-890L be a stable router?
wich one is better? or I just change to other brand?

I have a netgear FVS366GV3 this one is stable router because it got schedule reboot, I set it to reboot every 12hrs.
but the only problem of this router is their UTM firewall causes my ISP internet speed limit in below 30% wich netgear commited can't resolve this on their ProSafe line ups. wich my original internet speed is 100Mbps down/Upload speed only gets 30Mbps below and also the port forwarding problem not user friendly.

If your having problems with different router and they all seem to be doing the same thing, then it maybe a environment or interference issue and not a router issue.

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion and Good Neighbour Policy

• Ensure the default (dlink) SSID name is changed. Ensure that different SSID names are used between each WiFi 2.4/5Ghz radios. Can be anything and not something that's already in use by any neighbouring WiFi routers. Under Setup/Wireless/Manual.
• What wireless modes are you using?
• 2.4Ghz and 5Ghz routers: Try single mode G or N or mixed G and N on 2.4Ghz and single mode N or AC on 5Ghz?
• Channel Width set for Auto 20/40Mhz or try 20Mhz only.
• Try setting a manual Channel to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear. 13 for EU regions. Try channel 48 or 149 on 5Ghz.
• What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES, so you might want to try TPIK only or Auto TPIK and AES.
• What wireless devices do you have connected?
• Ensure any devices with WiFi adapter drivers are updated.
• Any 2.4Ghz or 5Ghz cordless house phones or WiFi APs near by that maybe causing interferences?
• Any other WiFi routers in the area that maybe causing interferences? Link> Use a WiFi Scanner to find out. How many?
• If you have any of these options, Try turning OFF or ON Short GI, WLAN Partition, Extra Wireless Protection and HT 20/40 Co-existence if you have it. Also testing with HT20/40Mhz Co-existence enabled will impact results as well. I prefer to use this option OFF. Recommended settings are default. Under Advanced/Advanced Wireless.

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.

Sounds like a modem issue. What model modem do you have?

Swapping to DIR-885L, will play with the schedule reboot to maitain my lan stable...

Reboot shouldn't be needed if your having the router do that all the time, the maybe something else thats causing the problem. I've never ever used scheduled reboot of a router.
