Are you finding mysterious downloads coming into your computer? It may be nothing sinister. But on the other hand… we’d better check the source.
Even a cached version of a website could send information about you back to the original server. The thing is that we just don’t (and can’t) know.
With one exception, having an open port is not dangerous. But the way that ports work is interesting!
When you are connected to a wireless network, but cannot get to the internet, it’s because an IP address has not been assigned to you. So how do you fix that?
Some smart routers can act as a local DNS servers in an attempt to speed things up.
Hotels and other hotspot providers often insist that you agree to some terms of service before you can use their internet. The problem is that insistence can often interfere with the connection.
Finding out that you are on a blacklist can be a nightmare. So how do you get off of it?
In this scenario, you’ll end up with two IP addresses, but the hub and router won’t each get one. I’ll explain.
Many things can interfere with a network speed test on your end. Make sure your speed test gives you the most accurate results by following these guidelines.
I have a rant about hotels that nickel and dime you on an internet connection. Fortunately, there might be something that you can do about it.
The communication path between two end points will be the slowest piece of the connection path. That will be the maximum speed that you can achieve on any network.
There are several ways websites can reasonably approximate your location and serve up ads specific to locale. We’ll look at each.
Without a doubt, having lots of tabs open can impact a computer’s speed. Whether or not it slows down the entire network will depend on exactly what all those tabs are doing.
The fact that your extender isn’t giving you access to set up security concerns me. I don’t believe it’s common and I’m really surprised it’s not there.
Trying to control children’s access to the internet has been a problem since computers first came into the home. A simple low-tech answer might be the best.
Comparing your machine’s IP address to that reported by a website may result in a surprising difference. I’ll explain why that is and why it’s a good thing.
DHCP stands for Dynamic Host Configuration Protocol, and is how computers request and receive “dynamic” IP addresses as well as additional configuration information.
Unfortunately, network sniffing is a very simple thing to do and it has actually nothing to do with the network discovery option.
This IP address looks like both the IPv4 address and the IPv6 address that’s been assigned to that particular network node.
NAT is a fundamental technology used by routers allowing you to share internet connections and stay safe. I’ll give a conceptual overview.
Everyone wants a faster internet connection. I’m frequently asked if it’s possible to combine two or more connections for speed. The answer is yes … but.
You hear a lot about the wireless internet, but it’s not something you can just connect to anywhere. It’s more often something you purchase and set up.
We’ll look at some of the specific information you’re making available to every website you visit, and briefly explain each.
“Limited Connectivity” displays when your computer is having problems completing its network configuration. It might as well mean “no connectivity”.
I frequently hear from people who are quite insistent that they be able to trace an IP address to the person behind it. It’s just not that simple.
Two computers should never have the same IP address if they’re on the same network. If they do, results are unpredictable.
If there is a conflict with your IP address, it could result in only one of the machines on your network working at a time.
Network adapters often try to detect the network speed for you. This can cause problems if both sides are trying to auto-detect at the same time.
