    Best answer: To get WiFi, you need to buy a wireless router designed for home use. Power it up and configure it as you want it and it will give you WiFi. If you want access to the Internet, which is a service that can be carried over a WiFi connection or a wired connection such as Ethernet, then you need to sign up with an Internet Service Provider (ISP). Some ISPs will supply a modem and a router for use with their service. (A modem is a device to convert the analogue connection from the ISP into a digital connection required by the router.) Remember, WiFi and the Internet are not the same thing. You can have a wired connection to the Internet without WiFi, and you can WiFi without any access to the Internet. Many people do not understand this and unfortunately seem to believe that WiFi and Internet mean the same thing. I hope this helps.

    Best answer: There are two ways your eyesight can be affected by close work and may require optical correction at some point: 1) If you did a lot of very close work at a young age without doing much long distance viewing, then as the eyes could still have been developing. This can lead to short sightedness which can become apparent in middle to late teenage years. This can affect people who do a lot of fine drawing or small print reading as a young child, and obviously can affect people who spend most of theirs days using small screens in those early years. Watching TV from normal viewing distances should not be a problem. 2) Over the age of around 40, many people suffer from hardening of the lenses in their eyes. The muscles in the eyes that distort the lens shape to focus an image can struggle to focus to close distances and this can lead to tired eyes and an inability to focus on close objects clearly. Wearing glasses for reading can help with this. I started this way, but switched to varifocal glasses around 30 years ago so that I am not everlastingly putting fixed focus glasses on and taking them off again. There is another issue that can cause some discomfort. If you grew up looking mainly at distant objects, your eyes will have a parallel view by default. When you look at closer objects, the eyes have to turn inwards so that they are both focussing on the same near object. Squinting is a deliberate attempt to turn the eyes inwards. Holding this position for long periods can cause some discomfort; however, this is not true eye strain. It is possible to get glasses that can correct for this, but they are not very common. Take a break every 30 to 60 minutes where the break time in at least 10% of the session time (at least 3 minutes every 30 minutes as an example). I hope this helps.

  • How do you change your IP address of your router?

    Best answer: ISPs normally assign a single public IP address to each home Internet connection. With IPv4, there are simply too few addresses for every device to have a public address of its own.

    Best answer: ISPs normally assign a single public IP address to each home Internet connection. With IPv4, there are simply too few addresses for every device to have a public address of its own. Your router has a feature called Network Address Translation (NAT), or more accurately Network and Port Address Translation (referred to as NAT and PAT). When you make an outgoing connection to a website, the NAT function changes your computer's local private IP address into the router's public address on the Internet (or in some case such as in an apartment block, to an address on another subnet covering the different apartments). The router remembers which addresses (source and destination) and which ports (source and destination) were used by the computer and by the router when the connection goes out on the Internet. When a response comes back, the router checks the addresses and ports (although source and destination are swapped over) and does the reverse mapping. If a computer on private address 192.168.0.11 with source port 12345 opens a connection to an http site on address 123.123.123.123 port 80 (the http port), the router will change the 192.168.0.11 to its public address (say 111.222.112.221). The destination address and port are unchanged. The source port may not be changed; however, if another computer on the private network (192.168.0.12) opens an http connection to the same website, and by chance is using the same source port number, then there is nothing to tell the site that it is a different connection. In this case, PAT comes into play and the router changes the source port number to one it is not using on the Internet. When the response comes back reverse NAT and PAT can route the response to the correct computer. Although the destination port on an outgoing connection is normally predefined (80 for HTTP, 443 for HTTPS, 25 for SMTP, etc) the source port is picked at random by the source computer's operating system from the higher numbered ports. Open two connections from two tabs in a browser with both connecting to the same site, and the connections will have different source port numbers assign by the operating system. This will happen even without a NAT/PAT router being present The NAT function in the router is why all computers on a home network can have the same public IP address. Depending on how your ISP assigns and manages public addresses, your public address may never change. It may change spontaneously normally only at a maximum of perhaps twice a day unless you disconnect from the ISP. Disconnecting from the ISP for a period of time can mean the ISP will assign that address to someone else and you will be assigned a different address when you reconnect. Generally there is no need to change your public IP address. If your router is working correctly, it will only let in packets from the Internet that are responses to outgoing packets. If you want to run some form of Internet accessible server, then you will have to configure port forwarding that will tell the router to allow packets arriving on the public IP address with a specific port number, such as 80 for an HTTP web server, to send these packets to the specific computer on your internal network that is hosting the HTTP server application. I hope this helps.

    Best answer: Your hotspot will be a WiFi network offered by your router. Although you can choose not to use any encryption, there are basically four groups of encryption: None (which I guess is what you currently have) WEP WPA WPA2 These are in order of potential security with WPA2 being the most secure. WEP can normally be hacked in a few minutes by a skilled hacker. WPA is much more secure, but does have a known security flaw. WPA2 addresses this security flaw. If the router offer options, use WPA2 (PSK) with the AES algorithm. WPA2 with a good pass phrase is virtually unbreakable. You should pick a good random pass phrase. For WEP this is limited to either 5 or 13 characters, but WPA and WPA2 the pass phrase can be between 8 and 63 characters in length. I recommend using a pass phrase of at least 20 characters, made up of a random mixture of upper and lower case letters, numbers, punctuation and any other symbols on your keyboard. Set up the encryption and pass phrase over an Ethernet connection. If there are any problems, you can correct them over Ethernet, but may not be able to fix them over a WiFi connection. If the router has WPS for easy WiFi set up, turn it off. This is also a security weakness. Some routers allow you to hide the network name. Personally I do not recommend this. It has minimal effect on security, and it can mean that other nearby networks do not detect your network and can establish a rival network on the same channel. I hope this helps.

    Best answer: I have only had direct experience of this being implemented using a server farm and thin client approach. All the main processing was done in the server farm, and users simply logged on from whatever PC or terminal they were sitting at. That also allowed mobile and home users to log on and sign in to there accounts from anywhere in the world that gave them full Internet access. When I was working from home, I could log in and open and work on files I had been using a few hours earlier in one of the company's offices. I had an application on my home PC that provided a secure connection and front end into the server farm, but allowed me to run normal Internet traffic from the PC as any home user would do. (I could also open up a browser in a farm server and hop on to the Internet from there, although this was restricted to certain specific users who had a business need for Internet access.) From memory (I retired over 10 years ago) the software was called the Citrix Thin Client system. It had the advantage that any old PC built from the early to mid 1990s could be used as a terminal on the system. In the office, my desktop PC had a 500 MB disk and 16 MB of memory and was running Windows 98. I hope this helps.

    Best answer: I assume you are trying to reach a website that is not normally accessible using your ISP's DNS server, or you are trying to access media that is not normally available where you live. There could be a few reasons: 1) The DNS you were using has updated its cache and is now returning a different IP address from the one it provided previously. 2) The site concerned has changed its IP address, and the DNS is still returning the old IP address. 3) The site is currently not working. 4) The site has started rejecting connections from the country where you are located. 5) Your ISP is blocking the DNS servers you have entered. 6) Some malware may have put a rogue entry in the phone's hosts file. Entries in the hosts file take precedence over any DNS servers. When everything is working correctly, it should make no difference which DNS server you use. Theoretically all DNS servers should return the same information. If they do not have the information cached, then they should load their caches from other servers. If you use a none standard DNS, then there is no guarantee that this will be correctly tracking any changes of IP address that a site may make. Changes of IP address can happen because a site physically moves to a different location or because the site has changed its ISP. Normally the DNS details would be amended some days before such a move to reduce the TTL (Time To Live) of cached entries down to a few minutes. After a few days, the address change would take place, and the site would disappear for the new short TTL time. After this the TTL could be put back to a more normal figure often set at 7 days. If you use a non-standard DNS, then there is no guarantee that it will observe these procedures. What happens if you let the iPhone get all its addresses automatically from the router? Having multiple WiFi networks should make no difference. Your phone can be connected only to one, and your phone will still be accessing the same DNS server(s). Try deleting the profile for your WiFi connection, then reconnecting to the WiFi network without making any manual changes to the address settings. Finally, when you ask a question like this, it is always helpful if you include details such as where you are located, the site's URL you are trying to reach, the DNS server address(es) you are using, and the reason you are not using your ISP's DNS servers if you set up DNS entries manually. The URL and DNS server addresses will allow others to test access to the site. If others can get through, then the problem is with your ISP or your own network and devices. I hope this helps.

    Best answer: It makes no difference whether devices connect to the router by WiFi or Ethernet assuming the router supports both, which most do. You will probably have to set the DVR on a static address on your private network, and then configure port forwarding in the router to allow connections from the Internet to that static address. If your ISP provides a dynamic (changeable) public IP address, then you will probably need to use a DDNS service such as dyn.com or noip.com (there are others). This will give you a fixed URL that will point to whatever public address you currently have at home. You will also need a DDNS updater. Some routers include this facility. If your router does not, then you will probably have to run a PC with an updater App installed so that the DDNS server knows your current public address. If you go away and the ISP changes your public address 10 minutes later, you need to be able to conenct to the new address. I hope this helps.

    Best answer: There should be no problem putting a 1.65 GB masterpiece on a 4.7 GB DVD. You say that the laptop was updated. Does the DVD drive do anything now? At least the Windows DVD writing software should still work. There are two ways of putting a video on to a DVD. The first is to copy it as a data file. Although this will play on a PC, it probably will not play on a TV's built in DVD player. The second way is to master the DVD. This will convert the file into a format that normal non-computer DVD players can handle. My suspicion is that as part of the update to your laptop, the drivers for the DVD drive are either missing or are not compatible. If nothing works with the DVD drive, then go into Device Manager and see if the DVD drive is showing some form of error when you open its properties. If it is a driver problem, see if you can download and install the proper driver for the DVD drive. I hope this helps.
