Title: wireless access point dissapearing
Post by: silent2nja on May 10, 2012, 12:38:44 AM
Anyone else have this problem? I've setup the router pretty standard, didn't change any of the advance settings, but the wireless access point often suddenly disappears and my PC gets disconnected. Then it reappears 10-30mins later, but the router itself is on the whole time. The way I got it setup is it connected to a router+modem right next to it and a nas connected to the ethernet. Any help?

What wireless modes are you using? Under Setup/Wireless/Manual.
Try single mode G or mixed G and N on 2.4Ghz and single mode N on 5Ghz?
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 (http://www.metageek.net/) to find out.
Turn off WISH, and WPS under Advanced.
Turn off Short GI, WLAN Partition,and Extra Wireless Protection if you have it. Under Advanced/Advanced Wireless.

 Setting channel manually is important.  I'd been using auto-channel for a while but had been having a lot of trouble holding a steady connection despite every spot in my apartment being within 25 feet or so of router. I downloaded a free app on my Android phone called Wifi Analyzer https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer&hl=en (https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer&hl=en) to scope out interference from neighboring access points.  (My phone, an HTC Rezound, has both 5GHz and 2.4GHz wifi radios) Watching the signals for a course of several hours, there are at least 20 access points within range of my apartment.  Then, I noticed that most of my neighbor's access points were using "auto" on their respective router's channels.  The funny thing was that the routers were sort of "running around in packs":  Everyone would switch to the channel that had the least interference for a period of time!  ::) So I put mine on a fixed, empty channel and, viola,  everyone stopped stepping on me quite so much.  My channel, since I was always on it, was never empty, so the "pack of routers" would change to the more empty space (where they were all stumbling on each other once they got there).  8)  It improved my signal by a lot, but my DGL-4500 was still not enough to overpower "Busy Panda", the router whose signal trounced all others--even mine :o, outside of a 5 foot radius.

I moved to an E4200v2 and my PC's signals improved radically--but Xbox Live support on that was AWFUL.  Now, after 5 months, I gave up on it, especially since the v2, just introduced in JANUARY is already DISCONTINUED in May.  Goodbye firmware support. Ugh.  Ordered a DIR-857 last night.  We'll see how it goes.

At any rate, the moral of the story is: pick a fixed channel and stick to it.  Use either 1, 6, or 11 on the 2.4GHz band.  On 5GHz in my apartment, there is NO interference at all (seems like no one in the complex has 5GHz...).  I wish all my devices had a 5GHz radio...if you have the option, that's even better.

Auto works in most cases, however like you said, being near by other WiFi routers will impact Autos ability to keep and maintain a channel, specially when there all being used up on 2.4Ghz. More and more areas are being congested with WiFi routers on 2.4Ghz. 5Ghz is the way to go in some cases and if devices support it or getting 5Ghz adapters to upgrade them to. In some cases as well, lowering the power output of the router can help to, it makes the broadcast foot print smaller and helps lessen some of the interferences.
