How can I identify the right power cord for any electronic device?


Well hello there,
if this is about electric devices in general, it depends where you live, here we use 250Volts, but you have several power chords as i will show you.
5_3_2014_10_56_35_pm.jpg 5_3_2014_10_57_38_pm.jpgHere you see some variations.
But they both go for 220volts or whatever is coming out of your wall.
The one with 2 pins has only plus and minus, the other with a third pin is used with electric devices that needs to be secured and to make it safe in case it will fail due to over voltage or water leaks...

When your Q is about the Panasonic, there is only one power plug available to my knowledge.

If your Q is about power sources like a power adapter to change from whatever comes out of your wall to let say 12volt, well then i still have something to say to you...
Yes you have tons of different plugs and they all fit on some devices, but to be honest with you it's not a big problem but you need to know where to look, like: you have cellphone, the most of them (modern ones) can be charged on any usb port of your computer, this tell you that it only needs 5volt because usb is 5volt always, and i believe it will give 550mA, so you need to make sure your device is suitable for the job.
If you want to use a device that needs 24volt and 2A you can not power it up with a 12volt 2A or 24volt 650mA, but you can power it up with a 24volt 6A
Hope it helped you out

I am only getting 34-54 Mbps with my Linksys. I have a wireless adapter in my computer. It will go lower, but never than higher than 54 Mbps? I know i can get 100mbps because my Xbox does. Help me out!


Wireless Ethernet (802.11a or b or g) does not get the bandwidth you would get through a cabled connection. My guess is that you have an 802.11g network card in your computer and 54 Mbps is the top theoretical speed for that type of Wireless adapter. Cabled connections will give you the theoretical throughput of 100 Mbps. Also, since this Linksys device is not a Wireless access point but simply a switch, your computer doesn't actually connect to it. Most likely you are connecting to your cable or DSL modem. Most of these have a wireless radio built in.

54 mbps PCI Adapter Card limits my connection to 2 mbps


Wi if is the slowest form of connection and is shared with other devices. If you want good bandwidth you need to connect via ethernet cable directly to the router.

good luck !

The connection on the rear of the hub should go to a USB connection on the laptop, not a PS/2 connection. A PS/2 to USB adapter is used to connect a PS/2 keyboard or mouse to a USB connection.

I have a Q-Stor 7 port USB hub, Model QU2RCT7. I


I don't have the original power supply for my QU2RCT7 either, but most hubs use a 5v DC power adapter, typically with a 2A. (2 amp) rating. I'm using such an adapter with my QU2RCT7 and it works fine. Make sure the adapter you select is tip-positive (ie, the "+" terminal is the "tip," or center, of the connector).

Belkin 54 Wireless Internet Connection Problems


Hello,

If wireless adapter on the laptop is fairly old, you may need to update the drivers for the wireless adapter. Some older wireless adapters are not capable of properly communicating with WPA devices. Typically a driver update of the laptop resolves the issue. If not, try another wifi adapter and verify it is not the OS or laptop itself.

Good Luck.

Toshiba Satellite ethernet port disappeared...


I think you have answered your own problem, your wireless has possibly been zapped.
To test your ethernet adapter on your laptop connect it to a network hub, check the hub and see if you have a link light on the hub and or laptop..
To test your wireless router, connect it to a known working computer with a network card and check the router configuration, using the browser, if you cannot access it then its zapped.

Limited connectivity


If the network you are connecting to has wireless security enabled, try to remove all the preferred networks and reconnect fresh and enter your network key.

One possible cause for limited or no connectivity is the incorrect wireless password set on it.

After connecting to the usb, led lights up, then off, windows does not detect it.


Is the hub you mention, an extension from another usb port only, as the adapter may need to be powered and require a AC/DC powered hub to work.
