On a normal setup you would plug your modem into a router, plug your laptop into the router and set it up with all your DSL/Cable connection information as well as wireless on/off. If you only have your laptop, this device and your internet modem it may not give you the wireless connectivity you're looking for. This looks like it's just an access point which extends a current network you have.

I'm unsure of the exact part number here but using the model number I checked the manual. Hope this helps you to understand why you already wasted your money buying Lexmark, dont waste anymore of your time and effort trying to find a fix. Also all inkjet manufacturers should be forced to remove the unecessary waste of ink everytime one switches the pinter on and off.

There are many marketting models they could employ to recover the supposed subsidy on the printer. The best solution I can suggest is to leave ALL Lexmark kit well alone back at the shop where it belongs, However tempting the 'offer' and 'competitive prices' leave it alone, until they play fair, with more reasonable ink prices and the option to refill if that is your choice. Check it out, the directory is called Lx-CATS-33 and the file is IxeaCATS.exe The other reason why you are done for is that during the installation of the drivers you inadvertantly installed a Spyware program that reports back to Lexmark your serial number, usage and ink cartridge levels everytime you use the printer or the PC connects to the internet. So the printer is not going to be used anymore and something else DEFINATELY NOT A Lexmark will replace it very soon. My printer is only 4 months old and have printed no more than 3k lines in 10 letters and some webpages and already it has stopped printing untill I buy a new black cartridge!! Talk about blackmail!! I thought I bought the printer for printing not as an excuse to enter into a life time agreement to buy ink. If you updated your firmware, you are done for!! As you said the compatible ink cartridge was working ok and Lexmark knew it, hence you were probably instructed to update to a version that looks for a Lexmark specific key to id the cartridge and force you to buy the original ones.

Excellent of Lexmark to trap the public with their inflated prices for ink cartridges and the Chips inside each cartridge that do not allow refilling or the use of any other compatible cartridge.
