Try restarting your computer, if this does not help, restart your wireless internet modem, if you have one. if that does not help, there is likely something wrong with the software on your laptop and you should contact technical support.

Can 10GE Optical Interfaces of a Switch Work upon a Unidirectional Fiber Connection?


10GE optical interfaces of a switch cannot work upon a unidirectional fiber connection. A unidirectional fiber connection occurs between two 10GE optical interfaces when one interface is Down because the Rx fiber is removed, while the other interface is still Up because its Rx fiber can receive link_Up signals from the PHY layer.
A switch determines the status of a 10GE optical interface according to the IEEE 802.3ae standard. As defined in this standard, the MAC layer of a 10GE optical can send local_fault and remote_fault signals. A switch can determine the link status based on only the link status of the PHY layer or based on the link status of the PHY layer and the local_fault and remote_fault signals from the MAC layer.
On a Huawei switch, link status of a 10GE optical interface turns Up only when the link status of the PHY layer is Up and both the local_fault and remote_fault signals are 0. When two 10GE optical interfaces are interconnected and the Rx fiber on one interface is removed, this interface goes Down and the MAC layer of the interface generates a local_fault signal. Meanwhile, the local interface sends a fault signal to the remote interface through the Tx fiber. The remote interface receives the link_Up signal from the PHY layer and the remote_fault signal from the MAC layer. Therefore, the link status of the remote interface goes Down.

Offline status


The most likely cause for this OFFLINE status on the PC is which interface is selected on the printer.
I think the printer defaults to Serial interface, so if you are using USB ensure you select the USB interface via the control panel on the printer, similarly if the connection is parallel ensure the parallel interface is selected.
If the connection is serial, ensure the cable is of the correct pin configuration and ensure the serial interface is set up correctly.

Job Status Window Interface has stopped working.


The issue usually occurs if you are using windows xp drivers on a vista machine. It's strange that the error does not come up when printing from internet explorer 7.0.

There is a file on support.dell.com that you can run to remove any xp drivers and then run the vista installation file. that should take care of these error messages from the operating system.

you can copy and paste the following links to download and run the files :

Can't get an IP address over time.


Ok I have guessed a couple of things. Here goes.
the version of software 12.4 (3g) is very old
I think that you have DHCP configured on the AP

the cisco site lists loads of issues regarding DHCP and memory leaks in numerous guises with not only your IOS version but newer versions too.

the reason why I have homed in on this is that you say that the unit works for about a week then essentially stops until you reboot the AP. (I guess that you do this by power cycling not by issuing the reload command) in the short term you have fixed the problem.

I would suggest that you upgrade the IOS to something newer. the current version listed is 12.4(22)T if it's of any help.

lastly as you know when the system actually goes wrong. You are able to issue the reload command with additional settings so it could reload @ X date and time if NTP is configured or you can specify a time duration in minutes if preferred.

I can't think of anything else I afraid.

Not able to connect to internet


1. try to check the status of the connection:
make sure it is connected and the status does not say either of the ff:
a. local only
b. limited or no connectivity
c. limited access only

2. try to change the network name [ssid] and the network key [wep or wpa passphrase]
you can change this by accessing the ipaddress of the router or its user interface

3.try to reconnect to the new network name
and make sure the status says connected.

this is not a browser issue . it is with the connection set up.
