Wireless Issues
« on: June 07, 2012, 09:38:25 AM »

I've had the DIR-857 for about two weeks now, and am getting rather frustrated with it. I received the router the day after the firmware update was released (1.01), and upgraded before I did anything. For the most part, the router is set up on default settings. I have the wireless set up with a personal password vs. generated key, but that's about it for custom settings. I ran the set up wizard and only tweaked the auto-detect for connection type to cable (ISP is Time Warner Cable).

On to the problems. I have two hardwired devices (one PC, and my xBox), which don't have any issues. The wireless is where I randomly encounter problems. My iPad II connects fine and hasn't had any interrupted connection. However, my fiancee's laptop (running on XP SP3) has had a lot of intermittent connections. It detects the network fine, and attempts to obtain an IP, but end up with limited/no connection. Her Kindle Fire is doing the same. I reflashed the Firmware last night, and rebooted all devices, including the router. I powered everything down, powered on the router and waited till it was fully booted and running before I turned any other device on. Same as it's been, my iPad was fine, her kindle connected fine, but her laptop did not. Signal strength is great (full bars). Any suggestions? Is the 5G wireless causing issues? Is there a way to turn it off if it is (i couldn't find a way to do it)?

Wireless Installation Considerations

Try single mode G or mixed G and N on 2.4Ghz and single mode N on 5Ghz? You can turn off the 5Ghz radio under Under Setup/Wireless/Manual.
Channel Width set for Auto 20/40Mhz or try 20Mhz only.
Try setting a manual channel to a open or unused channel.
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.
What wireless devices do you have connected?
Any cordless house phones?
Any other WiFi routers in the area? Use InSSIDer to find out.
Turn off WISH, and WPS under Advanced.

Great. Thanks for the info. I'll try those settings later tonight and post with results.

Ok. So I've tried the suggestions, in combination and individual. No luck. Reset the router via the push pin on the back of the router and started over. Still no luck. I emailed DLink support with the details and what I've done so far. We'll see where this goes.

Any other thoughts?

Wireless items incl.: laptop (Windows XP SP3), Kindle Fire, and IPad 2. All intermittent connection, and sometimes my wireless network doesn't even appear on the wireless list of the device.

Any other WiFi routers around or near by?
This happen only on 2.4Ghz or on 5ghz as well?

Maybe someone can review your router settings with you using teamviewer if your interested. Its safe and secure.

A couple of neighbors have wireless, as they show up on connection scans (all secure networks). Happens both on 2.4 & 5 Ghz. Tried them individually, no luck. Reviewed all the "Considerations" per the link, and do not have anything close to the specs for interference. No house phone, just use our cells. Never had any of these issues with my DIR-655.

The response I received from Customer Support was pretty basic, so I replied and explained everything you suggested. I received a reply saying I need to call Tech Support for a higher level of support.

If I don't get any resolution from my call, I'm returning this router and buying the Linksys EA4500.

If you have other neighboring routers near by, find a unused channel that the others are not using and set a manual WiFi channel. Possible you getting some interference issues here.

Some other things to try:
Turn off ALL QoS or Disable Traffic Shaping (DIR only) GameFuel (DGL only and if ON.) options. Advanced/QoS or Gamefuel.
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Turn on DNS Relay under Setup/Networking.
Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking
Ensure devices are set to auto obtain an IP address.
Set Firewall settings to Endpoint Independent for TCP and UDP under Advanced/Firewall.
Enable uPnP and Multi-cast Streaming under Advanced/Networking.

Don't do it!  I'm the proud owner of a dusty EA4500.  Don't do it unless you're content having problems with everything (not an exaggeration).  UPnP is hopelessly broken on that router, and stability is terrible.  I had to reset the unit every 24 hours because it just crashes...even with today's firmware.

Regarding the 857 Set the router conservatively: pick all narrow channel widths for wireless to start off.  Also, assign different SSIDs for 5GHz vs 2.4GHz, then debug the wireless setup one band at a time.
