I was wondering why I have a wireless network that I can connect to and it says I have a great connection, but when I'm connected it doesn't allow me to browse the Internet or anything. Are there any settings or anything I could change to get the thing working.

Wireless piggybacking

05/12/08

I'm currently in the country with no means of regular high-speed Internet access. I have found that I can connect to various unsecured wireless networks in a range of about 2 miles with where I currently am. My question is whether this is legal or not. Computers are not my strong point. I just want to be able to access the Internet.

When the wireless to a satellite connection is slow

04/28/08

I have a satellite Internet connection. The modem is connected to my computer. I purchased a D-Link Router model WBRr-2310. I am connecting at a speed of about 1300, but the other 3 computers that use the router connect at exactly 54 Mbps only. I connected my laptop directly to the modem and it connected at about 1300 also. But when I went through the router again it went back to exactly 54 Mbps. I have exhausted tech support for the router and for my Internet connection.

I have a desktop PC running XP Home and a laptop running Vista. The desktop is connected to a router via a cable and the laptop is wireless. The broadband speed on my laptop can run up to 6Mb but my desktop varies from 0.3 to 1.8Mb. Why does my desktop run so much slower than my laptop?

Disinfecting a spyware-riddled PC

03/31/08

What do I do if I suspect someone is controlling my PC? When my IP address has been changed without my knowledge? My boot-up process is getting harder unless I unplug the Ethernet cable and the CPU is at 100% every time I open any program. There is also a new connection to the Internet that is between my connection and the net I know was not there a month ago. When I try to register my e-mail address the programs say it's invalid and does not match whatever it has to compare it to.

If it's Monday, the network must be down

I have a simple 40 user network that has Monday-morning sickness.

A Web site I go to periodically for reference and other information is now prompting me to enter a username and password for a "Weblogic" server.

When you keep losing access to your wireless access point

02/11/08

I typically lose signal several times in a row within the space of ten minutes. Then it seems to work for an hour or so, before repeating.

Speeding up a sluggish PC

01/28/08

My computer has been slowing down over the last couple of weeks. Now, I can browse the net but after a period of time the 'cannot find server' page is displayed, and i can no longer browse. This goes the same for Outtlook and any other program that accesses the 'Net. The only fix at this stage is to reboot, and everything runs fine for a while again. Also, Add/Remove programs is now only accessible in safe mode. ANY assistance would be greatly appreciated. I am running XP Pro with SP2, P4 CPU 2.40Ghz and 768MB RAM.

Building a VPN with Cisco ASA gear

12/17/07

The organization I work for recently bought a Cisco ASA 5510 and 3 ASA 5505s to replace some SonicWalls we have in a few group homes.

I have tried to test the ASAs from home; I have tried a few things but all were unsuccessful.

Rolling your own NAS

12/10/07

I thought of building a RAID system. The Yellow Box gives 2 TB but I could build a box with 2.8 TB for less money. The main feature I would like is to be able to turn on the box for a short time (to back, daily or weekly) saving power and to increasing drive longevity. It would be ideal if the box could turn itself on and off with a schedule. I have built computers before so the hardware is not too intimidating. The problem is I don't know Linux at all, just Windows.

Setting up a network for a new small company

12/03/07

We are a new startup company with five to eight employees. I know we need a server and office network, however that's it. I've looked online at different servers this has only made choosing one even harder. We are lost, I guess what we need is a simple server for our accounting software, printing, and e-mail/Internet. If possible, please be as specific as possible on the specs. We are a very small startup so it will need work with a small budget.
