WiFi + Wired connection

WiFi + Wired connection Icon

I was getting upset with the performance of my internet connection via WiFi so I moved my router to the computer (Windows 7 64-bit) and plugged it in directly via ethernet. It then had a ethernet connection and a WiFi connection going at the same time.

Which connection was it actually using? I assume it would be smart enough to use the wired connection since it has 100 mbps potential and the wifi has 54mbps. Was it actually using both at the same time? I assume I would max out at whatever my wired connection could do.

I would only get the faster of the two. But what if I connect to my home router with a wired connection, and then connected to another public wireless network at the same time? Could you get extra speed this way?


Share WiFi via second WiFi adapter?

Share WiFi via second WiFi adapter? Icon

Is it possible to use ICS (internet connection sharing) to share a WiFi internet connection via a second WiFi adapter? I have a long-range WiFi adaptor which will pick up a local hot-spot, and I'd like to share it with my other devices, such as an iPad.

I've set up the long-range WiFi adaptor on the host PC to be shared as in the ICS details above, and selected the built-in WiFi adaptor as the connection. I expected to see a new WiFi network appear on my iPad, am I missing something?


How to use a ADSL modem's wifi with a fiber connection.

How to use a ADSL modem's wifi with a fiber connection. Icon

I'm trying to achieve something which I think most might not have tried, starting with what I have

1.Type 2 adsl2+ cpe/iad modem-It has built in wifi.
2.A fiber internet connection.
3.A samsung smart tv with built in lan adapter (40 inch LED-no wifi but wifi ready)

Now the modem which I have mentioned above cannot be used with the fiber internet connection.So,it is just lying waste but I want to use my internet connection provided by my ISP through fiber connection with the modem so that I can use my modem's wifi and lan ports.

What I have done was connected my laptop to my modem's wifi and also to my ISP's fiber connection so my laptop is connected to both the networks and now I have tried to establish a bridge connection between the lan connection and the wifi connection I was successful and I was also able to share my internet connection(as shown in my laptop) but when I have checked for the wifi internet connection it is not there(Checked on my mobile-one x and ipad).

So is there any way so that I can do this.?Please don't suggest me to use a application like connectify or virtual router to share my fiber internet connection.

Now there is a another thing that I have mentioned above my Samsung tv now I have connected one of my modem's lan connection to my tv and tried to use the all share application(my laptop is connected to the same modem through wifi) in my laptop I have found my tv and the laptop connected to the modem(Control Panel\Network and Internet\Network Map)but my tv is not at all recognizing my laptop and my laptop is also not finding my tv(in the allshare application).

If my first problem of getting my internet to the modem's wifi is possible then I also want to try that for the modem's lan connection so that I can avoid the pain of buying a samsung wifi dongle which costs more than 10% of my tv's price.

PCI WIFI card as repeater?

PCI WIFI card as repeater? Icon

I have a switch box upstairs with my cable modem and a wifi router. Downstairs I have a PC that is hardwired to the wifi router. My PC has a WIFI N PCI card installed into it (was forced to use wireless connection until I had a cat 5 jack dropped).

Can I make the WIFI card in my PC act as a repeater to the WIFI router upstairs? Reason I ask, the WIFI router upstairs doesn't get great coverage all over my house and if possible, I would like to make my PC repeat the WIFI signal.
