Can't remove the CPU cover to install a network card
I'm trying to remove the cover to my Acer 8000-333A CPU so I can install a network card for DSL internet access. I recently inherited this computer from a friend who'd had a wireless card installed. I've unscrewed 3 spring-loaded screws from the back of the computer, and found the lock/unlock switch at the top left, but I can't get the cover off to reach the network card space. Please help! Thanks.

Try This: Unplug the power to the DSL Router for 20 seconds then plug it back up. Remove the power cord and battery from the laptop, then press and hold the power button for 30 seconds. Turn the laptop over and look for the screw on the Wireless Card Cover. Remove the screw and the cover (it may be a number of screws depending you your system) then unplug the antenna cables to the wireless card (normally a black and white or black and gray cable). Remember which cable goes where before you remove them. Remove the screw that holds the wireless card in the slot, then remove it. Put the Wireless card back in the slot and secure it with a screw. Put the antennas back on the wireless card and then the cover. Put the battery back in, plug in the power cord and reboot.
If the system still does not find your wifi card, the card might be bad.
*** Sometimes the wireless card will be under the keyboard or palmrest instead of the bottom of the computer.
sounds like your wireless network card is failing or has a bad connection. suggest you power down your laptop, turn it over and remove the access panel for the memory and network card. remove the memory to make easier access to the wireless card and check for loose connections to the board and the antenna. if this looks good take the card out, use an eraser and lightly scrub the gold contacts on the card itself. when all the contacts are shiny again reinstall and test again to see if the issue is resolved. (do not install the cover) if it is resolved, install the cover and if not you can buy a replacement for this for under 20 dollars on eBay. make sure you purchase one that is listed as buy it now and new in package. the drivers should but do not have to be part of the sale. here is a good listing.
If you have any problems let me know and please leave positive feedback for me.
Can you try reset the network card and also reset the modem by pressing into the little hole on it for like 30 seconds? To reset the network adapter card, you can right click on the network connection of your LAN connection and click on diagnose if you are using Windows Vista. Then you will see the reset network adapter card option. Or you can follow the steps on the following link. http://windows.microsoft.com/en-CA/windows-vista/Troubleshoot-network-adapter-problems
the internal wireless card has either been told in network settings to shut down every 10 mins or is faulty and needs replaced if you take the cpu and ram cover off the bottom the card with the grey and black (usually)wires attched to it is the wireless card also u might wnt to try rolling back the drivers or updating them even from acers website
It sounds like your network card was damaged by a power surge, most likely what brew the power supply too. When you power up the PC now the network card tries to start and kills the network line going to the router, when PC is off the card does not short and the router works like it should. You should be able to put a new network card in a open slot in the pc and connect that one to your router.
That would depend on how you would like to get the internet connection to your ACER.
Benefits: Faster connection, easier setup, more secure
Cons: Wires must be physically routed requiring drilling through walls or passing through vent openings.
What you'll need:
Cat 5 ethernet cable from router to ACER and to your HOST PC
Ethernet network interface cards (NIC) in both PC's
any length of cable exceeding 100-150 feet will likely need a network Hub to boost signal strength
Benefits: Wiless acces to host PC(no drilling through walls etc.) can connect multiple PC's by simply adding a wirless card to new PC
Cons: prone to interference, less secure, setting up security protocols can be cumbersome
What you'll need:
Wireless Router/Access Point(AP)
Wirless adapter for remote PC (ACER)
Someone who is knowledgable about Wireless security to setup the firewall settings in the router.
OK so now that you have the options you can decide which is best for you.
Ethernet : If your willing to drill holes or pass through vents this will give you a faster connection
Wireless: This makes for a no mess/no fuss connection but at the expense of security and potential interference from cordless phones etc..
If you need help setting up your Network connection after you decide which you'd like please feel free to ask.
