The Graveyard - Products No Longer Supported => Routers / COVR => DIR-657 => Topic started by: MacHawes on August 19, 2013, 01:12:44 AM

I have a few questions about my DIR-657 (V1.02). First, when I go to the advanced wireless menu almost all of the settings like- beacon period, rts threshold, fragmentation, etc are totally gone. The only options are wlan partition, wmm enable, short gi, and ht20/40 coexistence. This happened recently because I remember seeing those settings last week. I haven't changed any major settings on the router so I am confused as to why the advanced wireless settings disappeared. Also, my router is set to 802.11 N ONLY with WPA2 AES, but when I check what wireless devices are connected they show up as using 802.11 G even though the router is in N mode only.
Thanks!

- What Hardware version is your router? Look at sticker under router.
- Link>What Firmware (http://forums.dlink.com/index.php?topic=47512.0) version is currently loaded? Found on the routers web page under status.

- 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?
Wireless Configurations
Links>Wireless Installation Considerations (http://forums.dlink.com/index.php?topic=48327.0) and Managing Signal Congestion (http://forums.dlink.com/index.php?topic=53228.0)
- Ensure the default (dlink) SSID name is changed. Can be anything and not something thats already in use by any neighboring WiFi routers. Under Setup/Wireless/Manual.
- What wireless modes are you using?
- 2.4Ghz Routers only: Try single mode G or N or mixed G and N?
- Try setting a manual Channel (http://en.wikipedia.org/wiki/Wireless_channel) to a open or unused channel. 1, 6 or 11. 11 for single mode N if the channel is clear.
- What security mode are you using? Preferred security is WPA-Personal. WPA2/AES Only. Some WiFi adapters don't support AES (http://en.wikipedia.org/wiki/Advanced_Encryption_Standard), so you might want to try TPIK (http://en.wikipedia.org/wiki/Temporal_Key_Integrity_Protocol) only or Auto TPIK and AES.
- What wireless devices do you have connected?
- Any cordless house phones?
- Any other WiFi routers in the area? Link> Use InSSIDer (http://www.metageek.net/) to find out. How many?
- If you have any of these options, Try turning OFF or ON Short GI (http://www.smallnetbuilder.com/wireless/wireless-features/30969-what-do-80211ns-optional-features-mean-for-you), WLAN Partition, HT 20/40 Co-exhistance and Extra Wireless Protection if you have it. Recommended settings are default. Under Advanced/Advanced Wireless.
3rd Party Security Software Configurations
- Turn off all anti virus and firewall programs on PC while testing. 3rd party firewalls are not generally needed when using routers as they are effective on blocking malicious inbound traffic.
- Turn off all devices accept for one wired PC while testing.
Web Browser Configurations
What browser are you using?
Try Opera or FF? If IE 8 or 9, set compatibility mode and test again.
Try turning off these features in Chrome:
Top right corner, little bars for options > Settings > Settings (on left) > Show advanced settings.
Uncheck these:
Use a web service to help resolve navigation errors
Use a prediction service to help complete searches and URLs typed in the address bar
Predict network actions to improve page load performance
Enable phishing and malware protection
D-Link may have taken some of the extra configuration features out of the UI to make things more simplified on this model router. I have noticed that some features seen on other routers, are not the same on different model routers. I have noticed interesting behavior with the HT20/40Mhz Co-existence being ON.
