Question about Dell OptiPlex GX280 PC Desktop

1 Answer

My Optiplex GX280 just stopped connecting to the internet.

I purchased Cox Cable Highspeed and it worked perfectly for about two weeks, now I get a message that just says connecting. It just goes on and on. I have checked with Cox Cable and everything is working fine from their end. There just seems to be a problem with the Internet Explorer connection.

Try buying a cheap ethernet card so if it isnt that, that you dont wast any money. but remember when you do it remember to unplug all the cable from the computer.

Dell Optiplex Gx280 - cant detect two IDE hard drives


You should attach two hard drives on primary ide. Set both jumpers to cable select ( or one on end is master, middle one is slave). The one at the end of the cable is where your o/s should be. You could try putting the third on seconday, along with your dvd rom.

Can I use 2WIRE 2701HG-B router in COX internet connection

No. A router has 2 main interface types WAN (for the internet connection side, and LAN (for the home network side) the 'LAN' side often has up to 4 ports and wireless connectivity for the home network.

The most common routers available at electronics retail use a CAT-5 connection for the WAN ports and the LAN ports. Your DSL modem/router uses a phone line input for it's WAN port, which uses a signal type that is incompatible with the cable modem output.

If COX doesn't offer a router with the cable modem package, you can go and purchase and common brand of home networking router, and attach it to the output of the cable modem.

Upgrading graphics card onto gx280 motherboard

You need to find a "PCI Express" video card. Your Motherboard does not have an AGP slot. There are lots of them to choose from. Better to pay more now and get more memory on the video card than to regret the purchase and buy another one. IMHO

Dell Optiplex GX280 won't start. Fan sounds like a Boeing 757

If the processor is ok, you can just change the motherboard. Then look for a compatible motherboard that can accept your processor.

Modem pro

Get High speed for the love of god.

No just kidding, i know, some of us cant afford it at home.

Most likely the phone number that the modem dials into may need to be updated for your service provider. If i remember correctly, you usualy have a list of numbers in the modem settings pick a different one.

You can also call the provider and they will help you.

I would recomend just paying the $40 a month for a cable modem and high speed and hooking straight to your network ( NIC ). Dial up is slow and you spend more time messing with dropped connections and slow speeds.

If your in an area that doesnt provide it, then i feel bad for you.

Good luck

The 2wire dsl modem/router cannot be use with a another cable modem , since this 2wire device is also a modem/router and its made for the DSL conenction that's why it wont work with Cox cable, the best thing that you can do is to ask Cox to give a wireless modem/router like this 2wire so you can still use the wireless connection of your computer..

Hope that helps..........
