The USB port in your computer is not the new high-speed USB 2.0 version, and when you plug a USB 2.0 device in you will get that message. Most USB devices will still work but not give best performance. Just close the message window.

The network cable unplugged message can be disabled through the network settings. Normally Windows is set to display that message when there is no network cable connected. You can just ignore the message.

That message means that your USB is version 1.0, but your usb stick is 2.0. Dont worry 2.0 is also working with 1.0, but usb speed is just slower that shows up with memory stick or camera if you try copy files by usb but for wifi its not so bad problem. That second message means, that your network cable is unplugged from route, but you dont need that, if you use wireless.

How does Wireless Network work?


A wireless network is simply two or more computers linked together by invisible radio waves with the purpose of transferring data or sharing resources. The configuration is similar to cordless phones in that they can share one telephone line, which utilizes one central "base" station along with multiple handsets placed throughout the house. Wireless networking is an excellent solution because you don't have to deal with cables and it takes little effort to expand.
There are two kinds of wireless networks:
Ad-hoc mode: Each computer in the network with a wireless adapter can communicate directly with each other without the use of a router or access point. You can share files and printers with this method. However, it is more difficult to connect to networks - both wired and wireless. This mode is also known as peer-to-peer networking.
Infrastructure mode: Each computer in the network uses a router or access point to handle all data transfer and network traffic. You can easily access a wired network, whether it is a LAN or the Internet. For most home networking purposes, infrastructure mode is the best choice.

Wireless Standards
Wireless-B (802.11b) - Operates on the 2.4GHz frequency band and can transmit data at speeds of up to 11Mbps within a range of up to 100-150 feet. Wireless range can be affected by reflective or signal-blocking obstacles, such as mirrors, walls, devices and location, whether indoors or outdoors.
Wireless-A (802.11a) - Operates at the frequency of 5GHz, which is less crowded than 2.4GHz where telephones and microwaves may cause interference. Although the speed is up to 54Mbps, the range is only up to 75 feet. Wireless-A is incompatible with both Wireless-B and G because it operates at a different frequency.
Wireless-A+G (802.11a + g) - Linksys also offers dual-band products, in which routers and adapters are compatible with both 2.4GHz and 5GHz frequencies. Both radio bands work simultaneously, blanketing your wireless zone and bandwidth.
Wireless-G (802.11g) - Features the same benefits as Wireless-B, but offers 5X the speed at up to 54Mbps. Wireless-G currently offers the best combination of performance and value. You can mix Wireless-B with Wireless-G equipment, but you will lose the higher performance speeds of Wireless-G.
The chart below outlines the differences and features for each wireless standard, along with the activities that are best suited for each one.

Network Hardware
Once you've chosen the type of network (wired or wireless) for your home, here is the basic network hardware that you'll need:
Router: This is considered the heart of your network and is the device that routes all the traffic to and from the Internet to the various computers on your network. It lets you share files and printers, and provides a basic layer of security from Internet threats.

High-speed Internet Connection (either DSL or cable): You can purchase High-speed Internet service from your local telephone (for DSL) or cable company. Both types of connections are considerably faster than dial-up access. High-speed Internet is also commonly referred to as broadband.
Modem: Connects your Internet service to your computer so you can surf the Internet and access your e-mail. Depending upon what type of broadband service you have, you must purchase or rent either a DSL or cable modem. Or, you can purchase a modem from your local electronics retailer or e-retail store. Linksys offers a gateway router which is an all-in-one solution that combines the functions of a router with a cable or DSL modem so that two separate devices are not required.
Network Adapter: Allows your computers to connect to the network. If you already have a wireless or network adapter pre-installed in your computer, you may not need to purchase one. There are different types of adapters available, depending on if you have a desktop or laptop computer.
e7a2392.gif
For a Desktop Computer:
  1. A PCI Adapter - connects inside your computer, requiring you to remove the outside case.
  2. A USB Adapter - does not require you to remove the outside case since it simply plugs into a USB port on the outside of your computer.
c7b29da.jpg
For a Laptop Computer:
  1. A PC (PCMCIA) Card - about the size of a credit card and simply slides into a slot on your laptop computer. This type of card is recommended when using a wireless network setup since you can walk around without having to juggle an external adapter.
  2. A USB Adapter - simply plugs into a USB port on the outside of your laptop computer.
How Routers Work ?
The Router is the central component in connecting all of your computers and network devices together, allowing them to access and share one high-speed Internet connection. It organizes all of the devices in the home network so that they can communicate with each other and share information. A Router combines the functions of a switch, which organizes and controls data flow among your computers and network devices. A switch is best for wired networks that want to share files and printers, but does not provide Internet access capability.
A Router joins two networks, your home network and the Internet, passing information from one to the other. It also determines how the information is passed in the most efficient manner. The router's two main jobs are:
  • To make sure that information doesn't travel where it's not needed.
  • To make sure that information travels to its intended destination.
da2f5a9.jpgThe Router also provides security measures to your network which prevent outside users from accessing your private data. This is important because a high-speed Internet connection is always on, which makes it more vulnerable to attacks from hackers. You may already have a basic software firewall installed on your computer, but the network can still be easily broken into.

Connecting Two Computers Directly With Cable for a home network


The simplest and easy way to start a home network 


The simplest kind and easy to maintain of home network contains exactly two computers. You can use this kind of network to share files, a printer or another peripheral device, and even an Internet connection. To connect two computers for sharing these and other network resources, consider the options described below.
Connecting Two Computers Directly With Cable

The traditional method to network two computers involves making a dedicated link by plugging one cable into the two systems. Several alternatives exist for networking two computers in this manner: Ethernet crossover cable
Null modem serial cable or parallel peripheral cable
Special-purpose USB cables
Ethernet crossover cable
Null modem serial cable or parallel peripheral cable
Special-purpose USB cables
Ethernet - Of the above choices, the Ethernet method is preferred as it supports a reliable, high-speed connection with minimal configuration required. Additionally, Ethernet technology offers the most general-purpose solution, allowing networks with more than two computers to be built fairly easily later. If one of your computers possesses an Ethernet adapter but the other has USB, an Ethernet crossover cable can still be used by first plugging a USB-to-Ethernet converter unit into the computer's USB port.

Ethernet crossover cables

Serial and parallel - This type of cabling, called Direct Cable Connection (DCC) when using Microsoft Windows, offers lower performance but offers the same basic functionality as Ethernet cables. You may prefer this option if you have such cables readily available and network speed is not a concern. Serial and parallel cables are never used to network more than two computers.

USB - Ordinary USB cables must not be used to connect two computers directly to each other. Attempting to do so can electrically damage the computers! However, special USB cables designed for direct connection exist that can be used safely. You may prefer this option over others if your computers lack functional Ethernet network adapters.

To make dedicated connections with Ethernet, USB, serial or parallel cables requires
each computer have a functioning network interface with an external jack for the cable, and
the network settings on each computer appropriately configured
One phone line or power cord cannot be used to directly connect two computers to each other for networking.

Connecting Two Computers with Cable through Central Infrastructure
Rather than cable two computers directly, the computers may instead be joined indirectly through a central network fixture. This method requires two network cables, one connecting each computer to the fixture. Several types of fixtures exist for home networking: Ethernet hubs, switches, and routers 
USB hubs
Phoneline and powerline wall outlets
Ethernet hubs, switches, and routers
USB hubs
Phoneline and powerline wall outlets

Implementing this method often entails additional up-front cost to purchase more cables and network infrastructure. However, it's a general-purpose solution accommodating any reasonable number of devices (e.g, ten or more). You will likely prefer this approach if you intend to expand your network in the future.

Most cabled networks utilize Ethernet technology. Alternatively, USB hubs can be employed, while powerline and phoneline home networks each offer their own unique form of central infrastructure. The traditional Ethernet solutions are generally very reliable and offer high performance.
Connecting Two Computers Wirelessly
In recent years, wireless solutions have enjoyed increasing popularity for home networking. As with cabled solutions, several different wireless technologies exist to support basic two computer networks: Wi-Fi
Bluetooth
infrared
Wi-Fi
Bluetooth
infrared
Wi-Fi connections can reach a greater distance than the wireless alternatives listed above. Many newer computers, especially laptops, now contain built-in Wi-Fi capability, making it the preferred choice in most situations. Wi-Fi can be used either with or without a network fixture. With two computers, Wi-Fi networking minus a fixture (also called ad-hoc mode) is especially simple to set up. How To - Set Up an Ad Hoc WiFi Network

How To - Set Up an Ad Hoc WiFi Network

Bluetooth technology supports reasonably high-speed wireless connections between two computers without the need for a network fixture. Bluetooth is more commonly used when networking a computer with a consumer handheld device like a cell phone. Most desktop and older computers do not possess Bluetooth capability. Bluetooth works best if both devices are in the same room in close proximity to each other. Consider Bluetooth if you have interest in networking with hand held devices and your computers lack Wi-Fi capability. 

Infrared networking existed on laptops years before either Wi-Fi or Bluetooth technologies became popular. Infrared connections only work between two computers, do not require a fixture, and are reasonably fast. Being very simple to set up and use, consider infrared if your computers support it and you lack the desire to invest effort in Wi-Fi or Bluetooth.

If you find mention of an alternative wireless technology called Home RF, you can safely ignore it. Home RF technology became obsolete several years ago and is not a practical option for home networking.

Try it is the best home network option.

Try disabling the onboard wireless adapter- the two may be conflicting w/ each other.

Devise can not be found when putting the dongle in


First I don't know what a bungle is....
But if you have a USB device and it is not beeing seen by computer, remove the device and reboot the unit.
Remove any external devices, such as usb mouse, usb wireless adaptor, ect.
Check your device manager for flags.. or unknown devices.
If you have any of the above with Red X or Yellow flags, remove them.
Reboot the unit.
Check the device manager again.
Plugin the Bungle.
If the unit is not seeing the device, try a differant USB port, as the port you are useing may not be a High Speed USB port and the device may require a High Speed Port.
If the device is still not being seen, check the device on another unit.
Hopre this helps.

When I plug a wireless cable into a USB port, the computer tells me that there are High speed USB ports available but does not inform where to find them.


Right-Click on My Computer, Properties, Device Manager, then Click on Universal Serial Bus Controllers, u will see the USB port available on your computer there. Also, at the same time you are doing this, try checking all the USB ports on your computer...most times, the HIGH-Speed USB Ports (USB 2.0) are always seperated from the other USB ports...so try the USB port seperated from others.
In your own case, Acer TravelMate 2303LCi has just 3 USB slots, a PC card slot, modem and network slot. No floppy drive, no TV-out, no IR, no Wi-Fi. So check-out USB Ports, the USB port infront of the Laptop beside the Audio Port and and the Speaker, on the extreme-right is your USB 2.0 High-Speed Port.

Usb upgrade


Let's see if I understand - you have added an additional card into the computer which adds USB v2 ports. Then I guess you are plugging a USB Wireless card into those ports.

Can you see the speed of the wireless connection? If you 't have an icon in the lower right hand corner for the card, hover over it with the mouse, or right click. Otherwise, go to Control Panel, Network Connection and look for the wireless card there.

Right clicking either one should show you the speed between your computer and the router.

Most wired connections will be 100 Mbps. Depending on the card and the router, wireless will be 10, 56, or 108 Mbps.

Wireless speed depends on many things, such as:
1) distance from the computer to the router
2) number of solid objects, such as walls, floors, or metal
3) possible interference from other wireless routers in the area

Do you think any of these are at work here? If you can reposition either the router or the computer, it may help.

Wireless is cool, but the best possible speeds will always come from a wired connection. I have my desktop computer wired, but my laptop wireless. When I go wireless, my speeds drop.

Tell me a bit about the equipment you're using, perhaps we can squeeze a bit more out of it.

Hope that helps!
