Older laptops do not connect with wifi
« on: July 05, 2013, 08:00:55 AM »

Last week I installed the DIR-857 with the original (automatic, DHCP, etc) settings.
It is connected to the internet via a Genexis hybrid Live! Titanium modem.
The internet connection is a 50/50Mbs fiber connection.

To test, I connected a Dell XPS-M1530 laptop temporarily direct to the fiber modem: speedtest: 49/48Mbs. So all oké with the modem.

As the DIR-857 connection to the internet was not stable, I upgraded the software from 1.00 to 1.04.
That helped a lot.

The 2.4Ghz wireless of the DIR-857 connected well with my Dell XPS-M1530 and Dell Insprion 15R SE laptops; throughput also oké (~45Mbs).
 
However, some unsolved problems:
 
1. I could not get a 2.4Ghz wireless connection up and running with my older Dell D600 lattitude laptop, neither with the Fuijtsu S-series lifebook (which has 802.11g).
Both do not connect while they do with my old DSL Thompson router.
I really need to connect those laptops.
What is wrong with the routers Wifi?
(I fear that mobiles and I-pad won't connect either)

2. The ethernet stays at 10Mbs.
Even with only a 1 meter CAT5e connection to only the Inspiron 15R SE, it stays at 10Mbs.
How do I get this running at 100Mbs?

I'm in The Netherlands.

Thank you already,
Bas

Link>Welcome!
  • Was a Factory Reset performed before and after 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?

Wireless Configurations
Links>Wireless Installation Considerations and Managing Signal Congestion
  • 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 and 5Ghz routers: Try single mode G or N 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. 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 TPIK and AES.
  • 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?
  • If you have any of these options, Try turning OFF HT 20/40 Co-exhistance if you have it. Recommended settings are default. Under Advanced/Advanced Wireless.
