Area 51 An Internet Connection Is Required __TOP__
In the early to mid-1980s, most Internet access was from personal computers and workstations directly connected to local area networks (LANs) or from dial-up connections using modems and analog telephone lines. LANs typically operated at 10 Mbit/s, while modem data-rates grew from 1200 bit/s in the early 1980s, to 56 kbit/s by the late 1990s. Initially, dial-up connections were made from terminals or computers running terminal emulation software to terminal servers on LANs. These dial-up connections did not support end-to-end use of the Internet protocols and only provided terminal to host connections. The introduction of network access servers supporting the Serial Line Internet Protocol (SLIP) and later the point-to-point protocol (PPP) extended the Internet protocols and made the full range of Internet services available to dial-up users; although slower, due to the lower data rates available using dial-up.

Most broadband services provide a continuous "always on" connection; there is no dial-in process required, and it does not interfere with voice use of phone lines.[18] Broadband provides improved access to Internet services such as:
Data rates, including those given in this article, are usually defined and advertised in terms of the maximum or peak download rate. In practice, these maximum data rates are not always reliably available to the customer.[29] Actual end-to-end data rates can be lower due to a number of factors.[30] In late June 2016, internet connection speeds averaged about 6 Mbit/s globally.[31] Physical link quality can vary with distance and for wireless access with terrain, weather, building construction, antenna placement, and interference from other radio sources. Network bottlenecks may exist at points anywhere on the path from the end-user to the remote server or service being used and not just on the first or last link providing Internet access to the end-user.
When the Internet is accessed using a modem, digital data is converted to analog for transmission over analog networks such as the telephone and cable networks.[18] A computer or other device accessing the Internet would either be connected directly to a modem that communicates with an Internet service provider (ISP) or the modem's Internet connection would be shared via a LAN which provides access in a limited area such as a home, school, computer laboratory, or office building.
Many "modems" (cable modems, DSL gateways or Optical Network Terminals (ONTs)) provide the additional functionality to host a LAN so most Internet access today is through a LAN such as that created by a WiFi router connected to a modem or a combo modem router[citation needed], often a very small LAN with just one or two devices attached. And while LANs are an important form of Internet access, this raises the question of how and at what data rate the LAN itself is connected to the rest of the global Internet. The technologies described below are used to make these connections, or in other words, how customers' modems (Customer-premises equipment) are most often connected to internet service providers (ISPs).
Operating on a single channel, a dial-up connection monopolizes the phone line and is one of the slowest methods of accessing the Internet. Dial-up is often the only form of Internet access available in rural areas as it requires no new infrastructure beyond the already existing telephone network, to connect to the Internet. Typically, dial-up connections do not exceed a speed of 56 kbit/s, as they are primarily made using modems that operate at a maximum data rate of 56 kbit/s downstream (towards the end user) and 34 or 48 kbit/s upstream (toward the global Internet).[18]
Fiber-to-the-home (FTTH) is one member of the Fiber-to-the-x (FTTx) family that includes Fiber-to-the-building or basement (FTTB), Fiber-to-the-premises (FTTP), Fiber-to-the-desk (FTTD), Fiber-to-the-curb (FTTC), and Fiber-to-the-node (FTTN).[54] These methods all bring data closer to the end user on optical fibers. The differences between the methods have mostly to do with just how close to the end user the delivery on fiber comes. All of these delivery methods are similar in function and architecture to hybrid fiber-coaxial (HFC) systems used to provide cable Internet access. Fiber internet connections to customers are either AON (Active optical network) or more commonly PON (Passive optical network). Examples of fiber optic internet access standards are G.984 (GPON, G-PON) and 10G-PON (XG-PON). ISPs may instead use Metro Ethernet for corporate and institutional customers.
Fixed wireless internet connections that do not use a satellite nor are designed to support moving equipment such as smartphones due to the use of, for example, customer premises equipment such as antennas that can't be moved over a significant geographical area without losing the signal from the ISP, unlike smartphones. Microwave wireless broadband or 5G may be used for fixed wireless.
One of the great challenges for Internet access in general and for broadband access in particular is to provide service to potential customers in areas of low population density, such as to farmers, ranchers, and small towns. In cities where the population density is high, it is easier for a service provider to recover equipment costs, but each rural customer may require expensive equipment to get connected. While 66% of Americans had an Internet connection in 2010, that figure was only 50% in rural areas, according to the Pew Internet & American Life Project.[129]Virgin Media advertised over 100 towns across the United Kingdom "from Cwmbran to Clydebank" that have access to their 100 Mbit/s service.[29]
One way natural disasters impact internet connection is by damaging end sub-networks (subnets), making them unreachable. A study on local networks after Hurricane Katrina found that 26% of subnets within the storm coverage were unreachable.[157] At Hurricane Katrina's peak intensity, almost 35% of networks in Mississippi were without power, while around 14% of Louisiana's networks were disrupted.[158] Of those unreachable subnets, 73% were disrupted for four weeks or longer and 57% were at "network edges were important emergency organizations such as hospitals and government agencies are mostly located".[157] Extensive infrastructure damage and inaccessible areas were two explanations for the long delay in returning service.[157] The company Cisco has revealed a Network Emergency Response Vehicle (NERV), a truck that makes portable communications possible for emergency responders despite traditional networks being disrupted.[159]
Streaming video and videoconferencing require higher speeds. If these comprise a good percentage of your daily internet activities, you'll need faster internet service with low latency. A provider with a fiber-optic connection is the fastest and most reliable choice, with cable a close second.
McKetta recommends using a Wi-Fi mesh system instead that can more intelligently select channels and route traffic. For more information on how to speed up your internet connection visit, Five Ways to Increase Your Internet Speed.
Back to WiFi Connection: I searched in some forums and there are some people who seem to have the same problem like me. For example: -support-1/ForumPost/killer-wifi-kee... Alienware Forum - Killer wifi keeps losing internet connection
2. Suddenly the current application stucks because the PC has no connection to the Internet. After 10 secs, the WiFi symbol gets crossed out. Windows displays that I'm still connected to the router, but there is no Internet connection. (every other device is still connected and has internet connection though)
The Distributed File System Namespaces (DFSN) integrates different file shares that are located on a local area network (LAN) or wide area network (WAN) into a single logical namespace. The DFSN service is required for Active Directory domain controllers to advertise the SYSVOL shared folder.
AWS Direct Connect is a networking service that provides an alternative to using the internet to connect to AWS. Using AWS Direct Connect, data that would have previously been transported over the internet is delivered through a private network connection between your facilities and AWS. In many circumstances, private network connections can reduce costs, increase bandwidth, and provide a more consistent network experience than internet-based connections. All AWS services, including Amazon Elastic Compute Cloud (EC2), Amazon Virtual Private Cloud (VPC), Amazon Simple Storage Service (S3), and Amazon DynamoDB can be used with AWS Direct Connect.
If you have configured a backup IPsec VPN connection instead, all VPC traffic will failover to the VPN connection automatically. Traffic to/from public resources, such as Amazon S3, will be routed over the internet. If you do not have a backup AWS Direct Connect link or an IPsec VPN link, then Amazon VPC traffic will be dropped in the event of a failure. Traffic to/from public resources will be routed over the internet.
VPN connections use IPsec to establish encrypted network connectivity between your intranet and an Amazon VPC over the public internet. VPN Connections can be configured in minutes and are a good solution if you have an immediate need, have low to modest bandwidth requirements, and can tolerate the inherent variability of internet-based connectivity. AWS Direct Connect bypasses the internet; instead, it uses dedicated, private network connections between your network and AWS.
Yes. You will need a MACsec-capable device on your end of the Ethernet connection to an AWS Direct Connect location. Refer to the MAC Security section of our user guide to verify supported operation modes and required MACsec features.
