www.gateway.com 123 You cannot connect to the Internet The ISP may be having technical difficulties. Contact your ISP for technical support. See if the modem works with a different communications program. The problem may be with just one program. Review the troubleshooting information under “Internet” on page 115. Your 56K modem does not connect at 56K Current FCC regulations restrict actual data transfer rates over public telephone lines to 53K. Other factors, such as line noise, telephone service provider equipment, or ISP limitations, may lower the speed even further. If your notebook has a v.90 modem, the speed at which you can upload (send) data is limited to 33.6K. If your notebook has a v.92 modem, the speed at which you can upload data is limited to 48K. Your ISP may not support 48K uploads. Your fax communications program only sends and receives faxes at 14,400 bps when you have a 56K modem Current fax technology only supports a maximum send and receive rate of 14,400 bps. The modem is not recognized by your notebook Make sure that the line connected to the modem is working and plugged into the appropriate port on your notebook. For the location of your modem jack, see “Back” on page 9. If the modem shares the telephone line with another device, make sure that the telephone line is not in use (for example, someone is on the telephone, or another modem is in use). Use a different modem cable. Some telephone cables do not meet required cable standards and may cause problems with the modem connection. Shut down and restart your notebook. Run Windows modem diagnostics. To run modem diagnostics: 1Close all open programs. 2Click (Start), then click Control Panel. The Control Panel window opens. 3Click Hardware and Sound.

If no modem information is available, a white screen appears with no data, or if you get an error such as port already open or the modem has failed to respond, the modem did not pass diagnostics. The modem is noisy when it dials and connects When your modem tries to connect to another modem, it begins handshaking. Handshaking is a digital “getting acquainted” conversation between the two modems that establishes connection speeds and communication protocols. You may hear unusual handshaking sounds when the modems first connect. If the handshaking sounds are too loud, you can turn down the modem volume. To turn down the modem volume: 1Click (Start), then click Control Panel. The Control Panel window opens. 2Click Hardware and Sound. 3Click Phone and Modem Options.

Networks (wired) You cannot see the other computers on your wired Ethernet network Make sure that your Ethernet cable is plugged into the Ethernet jack on your notebook. Make sure that the other end is plugged into a router. For the location of your network jack, see “Right” on page 8. Make sure that all computers are plugged into a powered electrical outlet and turned on. Make sure that the router is plugged into a powered electrical outlet and turned on. Most routers have lights that indicate they are working. For more information, see the documentation that came with your router. Make sure that all computers on your network have the same workgroup name. Make sure that all computers are using the same Subnet Mask. If you assigned IP addresses to the computers, make sure that all computers have different IP addresses. For home networks, IP addresses should be 192.168.N.N where N is a number you assign between 0 and 254. The first N should be the same for all computers on your network and the second N should be different for all computers on your network.

CHAPTER 9: Troubleshooting 126 Your wired Ethernet network is running slower than you expect If your Ethernet network is running slower than you expect, check the speed of each Ethernet component. For best results, all Ethernet components should be standard Ethernet (10 Mbps), Fast Ethernet (100 Mbps or 10/100 Mbps), or Gigabit Ethernet (1000 Mbps or 10/100/1000 Mbps). A mixture of Ethernet, Fast Ethernet, and Gigabit Ethernet components will result in your network running at the slowest component speed. You cannot connect to your company network Every network is unique. Contact your company computer department or network administrator for help. Internet Explorer is unable to access the Internet Reset the power on your cable or DSL modem and your access point. This reestablishes communication between your Internet Service Provider and your modem and between your modem and your access point.

www.gateway.com 127 Networks (wireless) You turned wireless networking on, but it takes a while to connect When wireless networking is turned on, it automatically scans for available connections. The scan can take approximately 30 seconds to complete. Your connection on the network seems intermittent or your wireless network is running slower than you expect The speed of a wireless network is related to signal strength. Signal strength is affected by the distance between your wireless network devices, by radio interference, and by interference from natural obstructions such as walls, ceilings, floors, and doors. If your wireless network is running slower than you expect, you should check your network signal strength. If you find the signal strength is low, try moving to a new location to increase the signal strength. To check the signal strength: 1Click (Start), right-click Network, then click Properties. The Network and Sharing Center window opens. 2Click View status for the network connection. The Wireless Network Connection Status dialog box opens. The meter shows the signal strength for wireless networking on your computer if other computers with the same network name are within range of your computer. You are in a wireless network, you can see the network, but cannot communicate, send files, print, or get to the Web If your access point uses WEP, go to the Wireless Networking Properties window and make sure that both the WAP and the WLAN in the computer have matching WEP keys.Important Note any antenna placement constraints in the access point user guide because the speed of a wireless network is related to signal strength. Signal strength is affected by the distance between your wireless network devices, by radio interference, and by interference from natural obstructions such as walls, floors, and doors.
CHAPTER 9: Troubleshooting 128 You are in a wireless network, but no available networks are listed in the Connect to a network dialog box If the network you are attempting to access does not broadcast its SSID, you need to request the SSID from the administrator and add that network’s information into the wireless utility. You may want to try entering ANY as the SSID, which will make the computer try to auto-detect the network. Your wireless network is listed as a preferred network, but it has an “x” on it An x means your preferred network is not currently available or you are not currently in range to connect. Internet Explorer is unable to access the Internet Reset the power on your cable or DSL modem and your access point. This reestablishes communication between your Internet Service Provider and your modem and between your modem and your access point. If you previously accessed the Internet through a dial-up modem, Internet Explorer may not be set up to access the Internet through a network. Remove the dial-up connection in the Internet Options in Internet Explorer. You cannot see other computers on your network Your notebook may not have the same workgroup name as the other computers on your network. For more information, see “Naming the computers and workgroup” in your online User Guide. If your notebook was previously connected directly to your cable or DSL modem, and your ISP requires you to use a static IP address, your notebook is not set up to use a DHCP server. Modify the network properties so your notebook is set up for using a DHCP server. You cannot connect to your network If your notebook is a member of a domain at your workplace, you may not be able to connect your notebook to your home network workgroup to access shared files or printers on your home network.
