    on the terminals that do work it shows
    "NETWORKCARD Connected"

It sounds like IP conflict.i would suggest uninstalling both the devices and then installing it fresh 1 by 1 and then put up the ip settings once again accurately.this should solve the conflict problem.

Copy all network settings from the handheld that connects to the one that dows not connect,

Check the router settings, ensure that there is no security option allowing only selected IPs to the netwoer, in this case remove the security setting that filer IPs from router firewall.

    Also double ckeck that you are using the right network encryption key on the handheld that is not connecting.

    If the key is wrong you get an IP but you have limited connectivity (like in your case) and you cannot access the network.

    Another possible reason is that some other device on the network is getting same IP from the router, in this case you get an IP conflict and you need to change handheld mac address, this is not always possible.

    If you are using terminal software, check if "configure IP paramenters" is on, in that case you will also need to configure this option. Best thing to do is also copying this parameters from the working handheld.

    When that happens it is because there is limited connectivity.

    That means that for some reason the router has given a bad IP to the scanner.

    This often happens when there is an IP conflict, or the Router has a problem with the scanner MAC address, that determines the dynamic IP assigned to the device.

    Ways to proceed:

    1 turn off all devices connected to network, (computers, printers , etc.).
    Restart the router.
    Start first the reader with the network problem.

    If it still does not connect you need to check on the manual , and try the following:

    1 Assign a static IP and see if the scanner connects to the router using a static IP, the IP must be in your network range, check any IP on the network , if the IP is for example, the range is usually from : to

    That may not work on the WAN (Internet etc.), as many ISP do not support static IP.

    In this case put IP back to DHCP, and check on the manual if there is a way to change the MAC address on the scanner.

    If it still does not work, try the scanner on a different router, if this work replace the router.

    If the scanner does not work on a different router or network, then it looks like it has a defective wireless LAN adapter.

Metrologic ms9520 not scanning UPC's


The issue is likely due to the programming (or the lack of) of the scan gun. It is entirely possible that the UPC bar code is not configured in your gun as a valid bar code.

You can remedy this by programming the scan gun to recognize the UPC bar code (and any other bar codes you may need to scan). Use the link below to download the programming guides for this scan gun.

Hope this helps!

Symbol 9090-G barcode guns loosing wifi signal.


I have seen this many many times.

Your problem lies with this statement:-

"I can even see every one of the AP's on the gun anywhere in the plant."

In simplest terms - you basically have too much RF signal. If you have 2 AP's on the same channel and they can see each this will cause problems.

You need to tweak your wireless network regarding power settings and channels. It’s a lengthy and laborious task. Start by getting a site plan, noting all the AP locations, channels and power outputs. Then look for ones that clash and amend. There are a few tricks and tips to use, but it’s basically keep adjusting until at any particular location the hand held can not see any AP's that clash. For a very large site it can take a few days to keep tweaking settings.

Hope this helps.

I get a "Connection Rejected" error when I try to connect the scanner to a PC

This could be a number of reasons.

First check that there is no password set on the hand held device.

Go to Control Panel >> Password to delete.

You may also have to many Partnerships on the host PC. On host PC open up ActiveSync and then open File and Delete Mobile Device.

If that all fails try re-installing Activesync and the host PC.

If you have a DHCP server on your network then it would have picked up an IP. If you have setup a static IP set try and ping from a workstation on the same network to the device.

I have seen it on numerous occasions where the WEP key is not quite correct and associates with full signal strength, but there is no connectively to the network. Remove the profile and try again.
