Connect Two Computers To The Linksys

Wireless G Router Using The D-Link Adapters

Preparation For Wireless G Transfer

Connect Wireless Linksys G Router To Two Computers - No Internet - Use The D-Link Wireless Access Points.

Connect Two Systems To The Linksys Wireless G Router Using The D-Link Adapters

Disable All AdaptersExcept The D-Link

(Including The Ethernet Cat-5 NIC Adapter)

Disable All Adapters (On Both Host & Destination Systems) Except Your D-Link

Replace The Two Screen Captures Below - One From Each System!

Each Of The Two Systems Is To

Have A Share Folder

C:\Share

Create A Folder, Called Share, On Both Computers.C:\Share

Make Sure That User Group Everyone Has Full Access Control To The Share

Make Sure That User Group Everyone Has Full Security Control To Read & Write To The Disk

Once They Get There

Double-Check SharesIf Computers CS-3 & CS-1 Were To Be Used For The Transfer, You Should Be Able To Log Into CS-1 - Copy Files To The CS-3 Share & Delete Those Files.

You Should Be Able To Do

Likewise On CS-1. Check Them To Make Sure The

Shares Are Correctly

Configured!

Find A Folder (about 200 MB) To Transfer

Does Not Have To Be The Adobe Folder

C:\Program Files\AdobeC:\Program Files(x86)\Adobe

Select A Transfer Folder (About 200 MB); You Might Want To Use The Adobe Folder?Show The Folder. Show The Folder Properties. Show The Destination Share Folder On

The Other Computer. Replace The Screen Capture Below With Yours!
