Internet Service Provider and Modem Configurations
Cable What ISP Service do you have? Cable or DSL?
NA What ISP Modem Mfr. and model # do you have?
NA If this modem has a built in router, it's best to bridge the modem. Having 2 routers on the same line can cause connection problems: Link>Double NAT and How NAT Works. To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged. If the modem can't be bridged then see if the modem has a DMZ option and input the IP address the router gets from the modem and put that into the modems DMZ.
1500 - cable - checked Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values
NA For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

finding faster DNS not done Turn on DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench
Done Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.

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 on 5Ghz?

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.

Any cordless house phones?
Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?
