Wi-fi issues
« on: May 07, 2013, 06:30:15 AM »

I had problems with Wi-Fi since the factory default firmware (b53). AP channel could not be changed properly, wi-fi just dropping out AND DNS issues.
As of the current firmware (see below), Wi-Fi is working some time after the reboot. After several hours or a day, the DNS resolving is getting very slow. Sometimes, clients can't event connect to the AP.
Wi-Fi sits on it's separate VLAN.

Can it still be the Wi-Fi firmware issue or continuing the nagging VLAN problem which has been addressed now several times in the couple of last firmwares ?

The local support is joke.
First of all, as I private customer (without premium packages) I'm forced to call a tall number. After some 20-40m of waiting still nobody picks up and the price is 0.5U$D/min!


Firmware:1.05B73_WW
Region: Denmark, Europe
Connection: ADSL2+ thorugh a bridged DSL modem
Wi-Fi: WPA2 PSK

In other words, the "enterprise level" Wi-Fi router from Dlink cannot manage to have Wi-Fi working  ???

Be advised that the DSR series of routers are business class routers, and not designed or meant for home, private or small business users. If your looking for phone support for private or home users, then your better off with a DIR or DGL series router. The DIR/DGL work well for there intended design for the average user. The Business class support is intended for the business class users, not home users.

What wireless modes are you using?
2.4Ghz Routers only: Try single mode G or N or mixed G and N?
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.
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? Link> Use InSSIDer to find out. How many?

thx for the advice.

i think if somenthing works it works in a home in a small businness or in big bussiness unit.

i have tried all the channel.
2.4 ghz mode only ( we don't have 5 ghz device)

tryed also auto 20/40 or 20 mhz only

we have connected different smartphone (android and iphone) printers and some laptop.

i put a dir-655 as access point (configured in 2.4ghz auto mode mixed mode) and all the device can connect.

with the dsr-250n configured in the same mode device conncted but they go on internet very slowly.

an home router that make the work of a business class router.

Unless your on a 1st gen iPhone, iphones should work well on N mode as well. I would phone contact your regional D-Link support office and as about this.

Is this router in a home or business?

Could install the 655 as a AP and turn OFF the WiFi on the DSR until you get it working.

Let us know how it goes.
