Re: Jet Eye ESI-9900 networking problems

I bought a Hammerhead tablet PC from eBay that is running windows 95. It came with a docking cradle and an ESI-9900 Jet Eye IR adapter that has an ethernet port and a token ring connection. I am having a problem with creating a small network with my laptop that is running XP home (sp2). I have tried several different ways to set up the network and I cant get my XP laptop to find the tablet pc and vice versa. How do I set up a network for this? Thanks!

Re: re: Jet Eye ESI-9900 networking problems

I was one of the original developers on the 9900. You need ESI's IrLAN layer. From what I understand, Microsoft did not implement IrLAN for the IrDA stack in XP. It will not work.

Re: re: Jet Eye ESI-9900 networking problems

Start with the cabling. Check to make sure the Adapter LAN port is properly connected to your switch port and that you are getting a link light on both ends. It appears that this device can only run at 10mbps, so if the port is set to 100 or 1000, or even has the duplex set to full, you are not going to get a physical connection. Next, check to see if there is any diagnostic utility to confirm that the IR port on the table is infact communicating with the docking cradle. Since this product is 10 years old and the company has since been bounght by a software company, documentation has been very hard to find. I did mange to find a FAQ re: setup here: And two Microsoft articles mentioning that the IR driver has to be up-to-date in order to work: Next, check that you have IP and IP address and IP connectivity. This can be done via the command prompt by typing the following command: ipconfig /all If you do have an IP address, then try to ping the Windows XP laptop with the following command in the command prompt: ping NOTE: Replace the with the IP address of the laptop. This info can be obtained with the same ipconfig /all command listed above. If you get a response from the ping, thats good and means you have end-to-end connectivity. Then you will just have to check to make sure the microsoft client and file and print sharing services on installed and enabled on both the tablet and laptop. If you have folders shares on them, you should be able to go to Start -> Run and type the following and hit OK: \\\ NOTE: Replace the with the IP address of the other machine. If you did not get a response from the ping command, then you have an IP connectivity issue and will need to trouble shoot that further. That could be anything from bad drivers to misconfigured IP settings or DHCP settings. I know this seems like a lot, but there really could be any number of reasons why this is not working. To close, I will try to summarize. 1) Check the physical network connections on both computers 2) Check the TCP/IP network settings on both computers 3) Check the Microsoft Client & File and Print Sharing settings on both computers.

Authentication problem

Make sure your router and tablet support the same stanard. 802.11a,b,g,n or ac. Make sure you're using either wep, wpa wpa2 or no security. Most tablets will not support a pin on the router. Also gointo wireless settings and forget your network. Then try to re-authenticate to it fresh.

Two pc's at home online but cant see each other

Do you have more details? Wired or wireless? What OS is each system running (e.g., Windows XP Home Edition and Windows 7 Home Premium)? It could be the software firewall on either or both system is causing the issue. If that is the case they would just need to be configured.

How to adjust or can increase internet speed

If you are using Windows XP Professional then it is possible to squeeze an extra 20% out of your internet connection. By default Windows XP Pro holds back 20% of your Internet speed for various services like windows update and spyware checks.
If you want to tap into this locked speed then make the following changes: • Go to Start-> Run-> and type gpedit.msc • Expand the Administrative Templates branch • Expand the Network tab • Highlight QoS Packet Scheduler • Click on Limit Reservable Bandwidth and check the 'enabled' box • Then Change the Bandwidth limit % to 0 % Once you've done this click apply and restart your PC. After rebooting you will amaze a noticeable improvement in your net speed. goodluck....

Why and what is my PC continuously downloading from Internet eventhough I am not myself downloading anything. Kindly help. Thanks

Probably your PC is doing one of two things - it is either updating software, windows updates or antivirus or firewall updates, these can be turned off in the options menus for programs that are running, OR , it has a virus or spyware and those programs are updating and sending data back to their makers. Windows update is usually automatically enabled, to turn it off use control panel, administrative options, services.

You must have a network setup first

Then both the machines must be in the same subnet

for example PC 1 -

Both should be in the same work group  just click on properties in mycomputer to set a work group name this should be same on both machines

Now share your directories using sharing wizard

Good Luck
