Hi I've the same problem exactly like you. I've done alot of research, i've installed anything related, tried also the 1704 wireless driver but nothing. When i try to install the 1705, even directly or by extracting it opens the wizard, select language, then appears to load, opens a second Atheros window in the backgrond, and then it crashes without finishing installation.
The file you're mentioning, perhaps is my last chance, but i cannot find it anywhere when googling.
Could you please send me the link in my email address? firstname.lastname@example.org
Step 1) Go to this link and download the Dell System Software for either 32 or 64 bit Windows 7
Step 2) This is the Dell 1705 wireless driver. Link to my Google Drive storage in the event others read this and want to download. I forget where I found this file, but I think it was on the same site that I found the Dell System Software (link in step 1)
Hope that helps
Inspiron 11 3137: Pentium 3556U, 8GB G.SKILL RAM upgrade, 128GB Transcend SSD upgrade, running Win 10 x64
I have the same problem, tried locating the file, can't seem to find it...
Could you email it to me.....
Click on the Google Docs link in the earlier post. It says "No Preview" simply because you can't preview an .exe file. Just click the download link (a down arrow symbol) at the top of the page to download the file.
