Re: wi-fi connection does not work, though recognizes...
I had the same problem. This is a router problem. If you are comfortable with going in and re-configuring some things with your router , you maybe able to repair this. Try changing the channel your router is operating on. Make sure your router is not near a telephone or other device that may operate on or near the same frequency. This could affect your ability to be a able to connect via wifi.
A 6ya expert can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

The free Wi Fi router may have run out of IP leases on its DHCP server just when you were trying to connect the tablet. If the leases are as an example say one week long then if lots of people connect to the free wi fi they get a lease for one week. So if the device comes back within the week it already has an IP address assigned to it and works. If a new device comes along it has to ask the DHCP server via the WI FI to assign it an IP address. If all available IP addresses are leased from the WI FI router the device will not get assigned an ip address. Would suggest trying to connect the Tablet on another Wi FI system to test it works.
I had this happen on my mobile phone when I was in Surfers Paradise in a Coffee shop and suspected the lease time on the WI FI router was too long for the amount of short term customers using the coffee shop. (the staff had no idea on why the Wi FI was not working so it would have been pointless to try and explain this concept to them and how to change the lease time on the dhcp server) Also there is a limit to the simultaneous number of users on a Wi Fi frequency on one access point . Unless the WI FI uses multiple WI FI access points.
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 !
How to configure IP address of wi-fi connection on a Android Phone (Samsung Galaxy Tab)
Posted in: GadgetsTagged Under:Android, Galaxy, Samsung, Tab7 Comments
By default Androids phones (including Samsung Galaxy Tab) are set to
automatically configure IP address, Gateway, Netmask and DNS address of
wi-fi network. But if you want to manually assign IP address,
Gateway, Netmask and DNS address of wi-fi, here is how you can do.
Method below is described for Samsung Galaxy Tab, but it will work for
all Android phones.
On Home screen, press Menu key.
Tap Wireless and network.
Tap Wi-Fi Settings.
Press Menu key again.
Enable "Use Static IP".
After you have enabled "Use Static IP", you will be able to manually assign and configure IP address, Gateway, Netmask and DNS address of wi-fi network.
Wi-Fi settings determine whether iPhone uses local Wi-Fi networks to connect to the Internet.
Turn Wi-Fi on: Choose Wi-Fi and turn Wi-Fi on.
Join a Wi-Fi network: Choose Wi-Fi, wait a moment as iPhone detects networks in range, then select a network. If necessary, enter a password and tap Join (networks that require a password appear with a lock icon).
Once you join a Wi-Fi network manually, iPhone automatically joins it whenever the network is in range. If more than one previously used network is in range, iPhone joins the one last used.
When iPhone is joined to a Wi-Fi network, the Wi-Fi icon in the status bar at the top of the screen shows signal strength. The more bars you see, the stronger the signal.
Set iPhone to ask if you want to join a new network: Choose Wi-Fi and turn "Ask to Join Networks" on or off.
Join a closed Wi-Fi network: To join a Wi-Fi network that isn't shown in the list of scanned networks, choose Wi-Fi > Other, then enter the network name. If the network requires a password, tap Security, tap the type of security the network uses, and enter the password.
You must already know the network name, password, and security type to connect to a closed network.
Some Wi-Fi networks may require you to enter or adjust additional settings, such as a client ID or static IP address. You can type it manually by login onto the Belkin's network page using the browser and by copying the static and dynamic IP address.
If you are using a commercial Wi-Fi network that requires a special login or subscription, see this article for more information.
If you are in a location with multiple Wi-Fi networks, verify that you are selecting the correct network.
Verify that the Wi-Fi network settings are correct:
Tap Settings > Wi-Fi.
Locate the Wi-Fi network you are currently using and tap
You can configure network-specific settings, including IP address, DNS, and Search Domain settings.
Use "Forget this Network" to reset settings for this particular Wi-Fi network, including the password. This is also useful if you identify a network issue and want to prevent the device from automatically using this network in the future.
Use "Renew Lease" to acquire new IP address, DNS, and Search Domain information from the Wi-Fi network.
Note: If the Wi-Fi network uses MAC address filtering, you will need to add the MAC address to the access list for the Wi-Fi router. The MAC address for your device is listed as the Wi-Fi Address in Settings > General > About.
Hold the power button until "slide to power off" appears. Slide to power off your device. When it is off, press the power button to turn it back on.
Reset network settings by selecting Settings > General > Reset > Reset Network Settings. Note: This will reset all network settings, including passwords, VPN, and APN settings.
iPhone only: If you continue to experience issues, consider turning off Wi-Fi and using the cellular data connection instead of Wi-Fi.
If using a Wi-Fi router at home, refer to your user manual/documentation to assist you with some of these suggestions.
Check the manufacturer's website for your Wi-Fi router for firmware or software updates.
Verify the Wi-Fi router can broadcast an 802.11b/g signal. If using a 802.11n Wi-Fi router, consult the manual/documentation for how to configure the Wi-Fi router for 802.11b/g compatibility.
If you are using multiple WEP keys on your Wi-Fi router, try configuring your Wi-Fi router to use only a single WEP key.
Try or resetting (or turning off and then on again) your Wi-Fi router. Note: If your ISP also provides cable or phone service, check with them before attempting this step to avoid interruption of service.
Disable wireless encryption or security on the Wi-Fi router to rule out encryption issues. If this resolves the issue, try using a different encryption or security protocol.
go to settings and wifi...look for your network and tap on it. Join your network and if it is secure it is asking for the WEP key which is on the label of the router. Enter that kep and it should join. if it is truely an unsecure wifi you should be able to get right on by joining it.
You may be seeing full signal but it may be your neighbors or next door
I had that problem in the beginning with my iTouch.
Have you checked your IP address?
Try opening settings, then open Wi-Fi, then touch the blue circle with the arrow in it that's next to your Wi-Fi router's name.
Once you're looking at a screen with your network's name at the top and your iTouch's IP address in the middle, scroll to the bottom of the page and touch "Renew Lease", then confirm by doing it again on the popup.
Now, scroll back to the top of the page and wait a moment. You should see the IP address go blank and then a new number should appear.
Hopefully you're online, check by opening App Store or Safari.
Turn off your iTouch competely (hold the lock/power button until the "slide to power off" slider pops up, then slide it).
Next, turn off your Wi-Fi router and modem.
Wait 5 full minutes.
Turn on your modem, wait 2 full minutes.
Turn on your Wi-Fi router, wait 2 full minutes.
Turn on your iTouch.
If all that doesn't work, call Apple Care... 1.800.692.7753
If you have any questions, please feel free to call me.

First remove the SD Card, then remove the drivers for the SD card. do a soft reset. install the driver for the card. go to settings, system, then remove software and check tat the software shows up. Oh by the wy make sure you have the HP SDIO fix install first. ok make sure that bluethoot is off. Install the SD Card. now go to settings, then connections tap on connections. tap the Advanced tab, tap the Network Card. you should see the SD Card listed. tap the Card. the next screen ask if you want to set the IP address or have the server assign the IP. I leave it at the default and let the server assign the IP.
Tap ok 3 time that should close everything. and you should be set. if you have a wi-fi setup you need to tap on start then programs, then tap on "WLAN" this program is what you use to check your signal strenght and check if you are getting a signal from your wi-fi. Once the signal strenght is strong enough you will see that an IP address will be asigned and you will be asked if you want to connect.
