Problem with Dell Wireless 1704 802.11b/g/n

Hi All!

I have a problem with Dell Wireless 1704 802.11b/g/n in my Dell 17R Inspiron 5720. Speed of my wifi connection changing from 5.5Mb/s to 54Mb/s all the time. 

I`m using Windows 7 Ultimate x64 OS. Problem is with wifi card Broadcom 4356, another laptop (HP) has stable speed 150Mb/s. I tried different options of card driver and router D-Link DIR-320NRU,  but nothing have changed.

  Is anyone can help me, please??

Re: Problem with Dell Wireless 1704 802.11b/g/n

Hello Valik,

There are few steps I would like to suggest.
1. Check the distance between the router and the laptop.
If it is more than 30 feet, the distance can be the cause of the issue.

2. Try connecting to a different network.
If the connection on a different network if fine, the problem might be with the router or the network.

3. Updating the Wireless Drivers.
-- Click start.
-- Open Control Panel.
-- Open Device Manager.
-- Choose Network Adapters.
-- Uninstall the wireless adapter.
-- Restart the computer.
-- Download and Install the wireless drivers from the link mentioned below.

Choose the wireless adapter from the list and install it.
Restart the computer and check the functionality.

I would also recommend updating the BIOS to the latest version. Check the BIOS version on your computer (Start -> Run -> type “msinfo32” press Enter).
The link mentioned below, would help you to download and install the latest BIOS.

Re: Problem with Dell Wireless 1704 802.11b/g/n

Hello, Dell-Allan D!

Thank you for your answer. I have tried everything you suggested, but I still have the problem. All drivers are originally downloaded from dell.com  

Vendor Version : WLAN_6.20.55.49/BT_6.5.1.1785

Dell Version : A01

I think the problem is in the driver or in the Broadcom card. If I have another driver, I'll know what the problem is for sure.

Hello,

I would suggest forcing a network adapter to 10 Mbps Half Duplex.  Forcing a network adapter to a Half Duplex can improve the communication between the router and the computer it is connected to.
Please follow the link mentioned below.

Re: Problem with Dell Wireless 1704 802.11b/g/n

Hey Alan,

  Just picked up a Vostro. It has the same Dell 1704 b/g/n 2.4Ghz card. It seems to be a lemon. Wont connect at more than 26Mbps and im sitting right besides the router. My Sony Vaio, and Toshiba connect fine. This is a work laptop and im running out of patience. If i move away from the router, the connection jut drops.. and My other laptops and my iphone and Samsung and Blackberry connect fine... Gonna try to see if there is any Bios/Driver update.. Else gonna have to send this back or ask to change the wifi card.

Lance
