Hello I have purchased an Apple laptop. It's offering me a choice of 6 WiFi networks to connect thru. I don't have a clue as to which one to use. Can you please point me in the right direction. Thank you!

My daughter has a Nintendo 3DS and wants to connect it to the Internet for some sort of multiplayer game. I am clueless about this device and didn't even realize it was Internet-ready when I bought it for her. Can you help me get her 3DS online?

Compared with the dial-up connections that most web users were using up until just a few years ago, even the slowest broadband connections are capable of providing users with relative high speed web browsing. However, as speeds have gone up, similarly, so have the expectations of users, which mean people are now using their internet connection for much more bandwidth-intensive tasks. Tasks, such as downloading television programmes, streaming latest film releases or even making voice calls. Unless you have a fast, reliable broadband connection, and a well set-up network, you may encounter some bandwidth issues- such as slower downloading speeds or even frequently interrupted streaming, which will only become a nuisance.

While the most obvious step is to invest in a better broadband service, such as those offered by Sky.com (check out their latest broadband offers on the website), there are plenty of ways you can improve your existing connection- things you can do to improve your broadband speeds.

I have my iPhone set up as a personal hotspot through AT&T but suspect that using it via wifi slows me down and that if I could plug it directly into my computer, it'd work faster. Is that true, and if so, how can I tether my iPhone via USB to my MacBook and gain faster access to the Internet?

This is probably like remedial Mac OS X 101, but I just got a new Magic Trackpad and am excited to use it, but can't figure out how to have my iMac know it's there. Since it's wireless, there's gotta be some trick, but my wi-fi / airport system never sees it?

I took the plunge and added "personal hotspot" service to my AT&T iPhone and it seems pretty cool, but I'm not sure of the best way to tap into the personal hotspot wifi with my new iPad 2. I'm a bit afraid to just mess things up. Got any tips?

I'm trying to set up a secure wireless network in my house and want to filter devices based on their "MAC" address. What the heck is a MAC address and how do I find it on my Mac Pro desktop and MacBook Air?

Just upgraded to Mac OS X Snow Leopard and am a bit baffled: the icon on the top menu bar for airport wifi service now has an exclamation mark through it. What does that mean?

Hi Dave - I have a MacBook laptop, OS X, 10.5.6 I brought my laptop to work (3 blocks from my apt.) and I wanted to get onto the internet. I found a couple of wireless networks using my built in AirPort that did not require a password. The connections are unreliable and slow, and probably not secure, (it doesnt matter because I'm not doing my banking or anything - just surfing), but I got onto the internet.

Once home, I'm unable to find any none-password networks and can't seem to get back on the ones I found at work. Isn't there such a thing as "free wifi"? E.g. at Starbucks, etc. Where and how can I find a free network? Or, where and how can I find out network passwords (I don't want to invade anyone's privacy - just want to keep myself entertained at a boring job!) Also, how can I create MY OWN network? Even if it's unsecure, I'd like to be able to unplug my ethernet cable at home and bring the laptop into other rooms.

I'll admit up front, this might be a pride issue, but now that I'm running Windows Vista on my laptop I find that I don't know what to do when it doesn't pop up a window telling me that there's a new wireless wifi network available. How do I connect to a new network quickly and easily in Vista??

I've become a big fan of my Apple Time Capsule. WIth the Time Machine backup software, it lets me keep all of my computers backed up without ever having to think about it, which is awesome! I just read about a firmware upgrade, however, and am baffled: how do I upgrade the device?

One of the reasons I bought the Sony PSP was so I could listen to some of the radio broadcasts available via the Internet from Switzerland, where I grew up. Can you explain how I can do that?

I've written about this before, about how to connect your Sony PSP to the Internet, but I think it's worth writing about again, detailing one of the most common questions people have with their Sony PSPs: how to connect them to the Internet.

Starbucks makes a big deal out of the fact that if you get a Starbucks Card you also get free wireless Internet access at Starbucks stores throughout the United States. Nice, but how do you *do it*? When I connect it says I already need an AT&T or T-Mobile account?

When I first got my Macbook (actually, it's an iBook, I think) I tried to connect to a neighbors wireless network, before I got my own network set up. Problem is, every time I start up my computer, it wants to connect to her wifi network, not my own. How do I fix this?

With the rise of higher speed wireless networking technologies, from 802.11g high-speed wifi to the pervasiveness of bluetooth and its kin with short-range wireless communications, it's becoming more and more difficult to determine whether it makes any sense to pay to have Ethernet "cat 5" wire installed in a home or office. There are more considerations than just cost, however, including security and future flexibility. Making this decision yourself? Then read on...

I have an Airport Express device and would really like to use it to enable a wireless printer on my local network. I know it can do that, but I have no idea how to hook it all up. Can you advise? I have a Mac running Mac OS X 10.4.9 and an older Apple Airport Express.

I don't know what the story is, but sometimes I go to places and my Mac automatically connects to the wireless network, but other times it requires that I select the network. The password to the network is in my "keychain", but something's still missing... ?

I have just set up a wireless connection at home - whenever I log on it says that the connection is unsecure - how do I secure it? I have a new Toshiba Laptop and a Phillips Router. I saw something about a WEP key....where do I enter this?

Hey bro! I'm staying at a campground and when I connect to the wireless network, I get a warning that there are all these other computers connected from my PC-cillin program, and it asks me if I should trust them or not. What does it mean?

I've been reading about the newest wireless standard called 802.11n and am unclear whether it's a smart upgrade or not. My geek friend tells me that it's not an "approved" standard and that there's a risk that what I buy might not be compatible too. Is that true?

I have high speed Internet through my cable provider and am about to buy a palm pda, not one that has a phone in it though, anyway it says it can get on the internet with a wi-fi connection and has the wi-fi stuff installed on it. I want to know if you can use wifi with high speed wireless cable internet or what. and what is wifi, and where can you find it??? Thanks

I travel a lot and often find myself needing to chat with colleagues back at the office via instant message (usually MSN but sometimes Yahoo). Problem is, I really don't want everyone else in the café using the open wireless network from sniffing the discussion. Is there some secure solution that's easy and portable?

Hey Dave! I have a Sony PSP and was wondering if I buy a wireless base station how do you set it up and are there any programs that i have to install?

I'm not too sure what the differences are, but my brother asked me if the Sony PSP supports 802.11 "b" or "g" and I really don't know. He also asked if it can connect to a WPA-based network, or just a WEP network, and, again, I don't know. Do you?
