Gateway PC crashing when connecting to Wi-FI

Step one turn on PC directly connected to ModemsbSB6121 without Wi FI router being involved.
Step two go to Command prompt type in ipconfig (press enter)
Step three note IP address of default gateway and ip address issued to P.C.
Step four type in default gateway address into browser and log into Modem.
Step five look for DHCP Server and allocate IP addresses from at least 50 for example 192.168.0.50 starting ip lease ending ip lease 192.168.0.254
Step six connect Wi Router to P.C. via ethernet cable only - remove ModemSB6121
Step Seven shutdown and restart p.c
Step Eight go to Command prompt type in ipconfig (press enter)
Step Nine note IP address of default gateway and ip address issued to P.C.
Step Ten type in default gateway address into browser and log into Wi Fi Router
Step Eleven Change IP address on Router to 2 as example 192.168.0.2. (it has to match in that modem device would have been 192,168.0.1)
(if it was 10.0.0.1 make wi fi 10.0.0.2 make sure subnet mask is the same like 255.255.255.0)
Step twelve Change DHCP Server to off
Step Thirteen may need to set default gateway to MODEM IP address for example 192.168.0.1
Step Fourteen plug modem router into Wi Fi router may need to plug into WAN port on WI FI router .
Step Fifteen shutdown and Restart Computer
Step Sixteen go to Command prompt type in ipconfig (press enter)
Step Seventeen type in PING 192.168.0.1 (if this is modem IP address and default gateway IP addess)
All this above is to avoid IP address conflicts or mismatching
Subnet mask should be 255.255.255.0
either it uses 192.168.0.1 or it uses 10.0.0.1 make sure Wi FI router is set to different address to Modem Router.
I suspect either a clash occurs or your P.C gets a different IP range from ther WI FI DHCP server.
Happy troubleshooting !

Are you very far from the Wi-Fi Router?
Is your Wi-Fi enabled on the computer?
Can you connect using an Ethernet cable?

Recently had a coworker bring me a Gateway NE71B laptop.
Complaint: No wireless even using a VZW 4GLTE hotspot.
Observations:
; All drivers and devices are functional with no errors or conflicts.
; Wireless adapter has power and is not in Airplane mode.
; No wireless networks are visible even though there are normally as many as 12 networks available within the area.
; Wired Ethernet adapter works without issues.
Solution:
Turns out the BIOS was v2.05. After updating the BIOS to v2.13, wireless connectivity is functional. All locally available wireless networks (SSIDs) are visible.

Notes of caution:
; A failed BIOS update will invalidate your warranty per Gateway chat support rep.
; Ensure you have a fully charged battery before updating the BIOS.
; Ensure your AC adapter is plugged in and functional prior to starting the BIOS updater.

Accessing Facebook needs internet connection. Without any active connection, you will not be able to connect to internet.
Internet connection option for such devices:
Mobile phone:1. GPRS - settings will be coming from your mobile service provider, data rates will be deducted from your load credits.2. Wi-fi connection - needs active wireless connection from your modem/router/gateway. Charges will be applied via ISP 9internet service provider)
Laptops / computer / PSP:1. USB Dongles - this will use the gateway connection via BTS for its using the internet connection like the protocol of ISP.2. Wi-fi - Wi-fi connection - needs active wireless connection from your modem/router/gateway. Charges will be applied via ISP 9internet service provider)

Either that or the ethernet chip on the motherboard is failing - you will need to disable this one from the BIOS and install a simple PCI LAN card in its place

You need to configure your router.
For that Connect your router to computer with ethernet cable then you can access it with following default link.
http://192.168.0.1
or
http://192.168.1.1
If you are not able to access it with above ip then check your computers ip address gateway ip is your router ip try with it.
Then it ask for user name and password.
Type user as "admin" and password as "admin" or "password" or blank.
Then you can see configuration page of router.
Click on WAN settings and set those settings as your internet service provider settings.
Enable DHCP if you want to get ip from router.
Clickon wireless settings enable wireless then enable WEP Security then add WEP code .It isyour password to connect wi fi.Then save settings and restart router.
Then you can connect your wi fi network with that code.
Let me know if you need further assistance.
Thanks for using FixYa.

The unit can connect to the Internet by utilizing its 802.11b/g Wi-Fi, which is built in, for wireless connections or via a USB-to-Ethernet adaptor for DSL connections.
For your wireless connection or Wi-Fi, the 802.11b Wi-Fi has a data rate of 11 Mbits per second and has an indoor range of 30m or approximately 98 ft. The 802.11g has the same indoor range, however the data rate is at 54 Mbits per second. If you have an existing wireless connection or are in a Wi-Fi hotspot, the unit will connect to your wireless connection automatically out of the box. If you do not have a wireless network, however, you will need to have your wireless network subscription done or set-up first. Once you have wireless Internet access, you then search for your access point, put in your security settings and you’re good to go. It would also be advisable to have a wireless router for this so that you won’t have to shuttle the connection between your PC and your Wii. Another option would be to connect your Wii via the Nintendo Wi-Fi USB Connector. This accessory allows Nintendo Wii users who do not have an existing Wi-Fi connection or a compatible Wi-Fi network to create one through their broadband or DSL connected computer. This is inserted into your existing computer’s USB port and the Wi-Fi USB Connector acts as a wireless access point for the Wii. This allows the user access to the internet and to play Wi-Fi Connection games from Nintendo Online.
For your DSL connection, however, you will need to have quite a few things. You can use a WII LAN adapter to connect your Wii to your DSL modem. You can also use a router so that you can use your PC and your Wii at the same time. With the LAN Adapter though, to use or plug in the Wii, you must disconnect your PC. This can be quite tedious since you will have to plug in and out your PC and your Wii every time you need to use one or the other. A LAN Adapter is fairly cheap, but if you get a router, your PC and your Wii can go online at the same time, saving you the hassle of connecting one or the other when you need them. You can then hook up the existing ethernet cords to the back of the router and connect it to the Wii via a USB 2.0 cord.

i hope this helps

SO you are not able to connect tyo the wireless network.
what is the operating system on your computer ?

Seems like you need to verify that the web management interface is at the address your specified or that your PC is indeed wirelessly connected to the CWR-854.

The following suggestions assume you use Windows XP as your OS:

1. You need to connect to the CWR-854 via a network cable (one end connected to your PC the other to a LAN port on the CWR-854) initially.
2. You can try to access the web management interface at the IP address you expect, i.e. 192.168.1.1 or you can verify the IP address by finding the Default Gateway your PC is issued by the CWR-854 from:

• Right clicking on the tray icon of the network connection, choose "Status" then click on the "Support" tab to see the Default Gateway.
• OR click on "Start" then "Run...", type "cmd" then type "ipconfig" and read the Default Gateway value under the section for the "Ethernet adapter Local Area Connection".

Use the Default Gateway value as the new address to use for the web based utility if it differs from what you expected.

Well... That's an interesting problem.

Try changing the wireless channel that your router is running on via the web interface in the router. See what happens when you try to connect the "Tilt" then.

If that doesn't work, then find out if the Tilt is running on 802.11b or 802.11g. Disconnect all wireless devices from the router and change the router's Wireless standard to either B or G ONLY. (Whichever the phone is.) Connect the Tilt again without any other devices connected to the router. See if it reboots again.

Those are basics for now. I've never tried connecting a phone to a router like that before. Otherwise I would definitely contact your provider and ask them about it. Given that the WRT54G is the most common consumer-level NAT router on the market, they are sure to be having issues with it where other customers are concerned.

Unless another wireless device you have is causing the issue. But that is what you are trying to pinpoint with the above procedures.

Give it a go and see what happens.
