DIR-845L - My Mac kills my Internet connection
« on: September 20, 2015, 05:52:14 AM »

Hey!

I've got the weirdest issue. My Dlink DIR-845L has worked flawlessly for the past year. I have had Macs, PCs, phones, tablet, game consoles and media hardware connected to it on a daily basis without a problem. But now I got a Macbook Air from work and it has the ability to terminate my Internet connection. I have no idea how and why and it seems to be very random in when it does. For instance, using an extension in Safari may cause it, clickin***ouTube link embedded on a website may cause it, connecting to a different computer over remote desktop, starting an online session in a game, opening a specific website... Basically, I can surf the web for any length of time (seriously, anything from 30 seconds to 2 hours before any issues), then there's that one random thing that does it. If I go into the router settings and release/renew the IP, I get an Internet connection again. I can surf and do whatever for as long as I want but if I redo that one thing that killed it this time, I have no Internet again. Thus I can recreate the issue how many times I want. Also, if I try to do that one thing AGAIN later, say an hour later, it will NOT kill my Internet connection. Time seems to heal all wounds...

When I say "kill my Internet connection" I mean that none of my devices will have Internet connection.
When Internet goes down, I can't find anything in the router settings that indicates any issues with the Internet connection (please point me to where that would be).

Ive tried:
* Rebooting the device.
* Resetting the router.
* Updating the firmware.
* Switching between 2,4 and 5 GHz.

These issues ONLY happen with this one computer. This computer has not shown any similar issues on a different wifi.

Any ideas?

Link>Welcome!

  • What Hardware version is your router? Look at sticker under the router case.
  • Link>What Firmware version is currently loaded? Found on the routers web page under status.
  • What region are you located?
  • Are you wired or wireless connected to the router?
  • Has a Factory Reset been performed?
  • Was a Factory Reset performed before and after any firmware updates then set up from scratch?
  Link> >FW Update Process
  • Was the router working before any firmware updates?

Internet Service Provider and Modem Configurations
  • What ISP Service do you have? Cable or DSL?
  • What ISP Modem Mfr. and model # do you have?


Router and Wired Configurations
Some things to try: - Log into the routers web page at 192.168.0.1. Use IE, Opera or FF to manage the router. Besure to log into the Admin account on the router.
  • 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 and maintain consistency for applications that need to connect as well as mapped drives.
  • Ensure devices are set to auto obtain an IP address.
  • If IPv6 is an option on the router, select Local Connection Only under Setup/IPv6.

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.
  • 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 InSSIDer to find out. How many? Use v3, its free.
  • 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.
