    My ISP has changed my modem, now W8.1 can't connect well


    Hi, I have 10Mbit/s download and 1Mbit/s upload speeds. My ISP offered me to change for free to Optical Fiber, so I accepted. They came and changed my white modem:

    by this Optical Fiber "pack", a modem and a gadget that I think send the modem the optical fiber signal:

    Click image for larger version

    So here, my first questions is:

    1. Why the new black modem has 2 antennas? Does that mean that it has DUAL band and can work with both 2.4GHz and 5GHz?

    2. The power of the signal (how far can I connect to it) is better because is "new" hardware and it has 2 antennas? Or it's probably the same?


    3. Now, my REAL issue. I have a laptop, Windows 8.1 x64, and an Intel Wireless-N 7260. I also have a router in one of my rooms, connected to the modem via PLC (power line communication). I can ONLY connect to my modem if I'm in the same modem's room. If I go to the next room (less than 5m) when trying to connect, Windows says that "It can't connect to this network". I have another laptop with Windows 7 and it can connect from that room and from the opposite room of my house with no problem.

    So something's wrong with my laptop, laptop's antenna, new modem, drivers... or something.

    I've updated also my WiFi card drivers. And if I'm in the router's or modem's room, the connection is great (not always). As the problem could be the new drivers, I've tried out some different versions:

    -With the original drivers, it works better, but even sometimes it disconnects.

    -With drivers 16.0XXXXX I can connect to my modem farther, but not as far as with I connected to my white. My router's range is shorter.

    -With drivers 17.0.2.5, the last ones, my router's range is larger, but I can connect to my modem only from the same room

    I don't know how to solve this, and it's driving me crazy.

    Thanks!

    I've found 2 weird problems:
    A) In my router's room, sometimes I connect to it, and the speed goes from 10Mbit/s to 0Mbit/s, slowly, until there's no connection. Reaaaally WTF.
    B) When downloading nVIDIA drivers, I get peaks of 30-50Mbit/s, but ookla speed test always give me a solid 10Mbit/s (when the connection is working properly). I don't know if nVIDIA is not showing the right information, although the MB downloaded seem to say that I was actually downloadind at that speed.

    You do not have to load any software to connect to that Gateway. You just need to find the SSID that the Gateway's Wifi is transmitting and enter the Passphrase, which is usually on the label on the bottom of the unit.

    As for two antennas. Just allows for better connections with the unit. Has nothing to do with if it is a Dual or Single band unit.

    As for the speed. When you made the change. Your ISP installer should have gone through all of this with you.

    The dual antenna's means it supports MIMO. Multi Input Multi Output. It can run more than one data stream. To get full Wireless N speeds the router has to be set to use dual channels to get the 40 MHz channel width. The one my ISP supplied was set to single channel only, 20 mhz. Do you know how to, and have you tried logging into it and looking at its setup?

    No I haven't. I've just noticed something. I think this has nothing to do with Windows 8.1. I've tried to connect a W8.1 laptop to the modem, and it has worked perfectly, with the range it should be. So it seems that it's a problem of my WiFi card, WiFi driver or my laptop's antenna. I've asked Intel and they say I should contact to Lenovo and ask them about my problem. I have a Lenovo Y510P and a Intel Wireless-N 7260. I wish someone with this WiFi card could confirm me if it works great in his laptop and if it get stable good connection if he is far away the modem.

    Again, this has nothing to do with Windows 8.1. If it does. The only problem would be that Windows was allowed to load the Microsoft WLAN drivers. Which means that the Lenovo WLAN drivers are no longer controlling the wifi chipset.

    You should be able to see the new SSID of the new gateway. You can go into a Command window and type in (Without the quotes): "netsh wlan show all". That will show you all SSID's that your WLAN sees. Along with how strong the signal is. Also shows you active WLAN driver information.

    That's what I did, and when connecting, it says: "can't connect to this network". Something's wrong with my antenna, WiFi card or drivers. I can connect to this modem a W8.1 laptop, an android mobile, a W7 laptop, but I can't connect to it my Lenovo Y510P UNLESS I'm in the same room, so it's a WiFi range problem of my laptop, I think the antennas.

    Try rebooting the Gateway and see if the computer then can connect. As for Wifi range. You will need to either use plug in Wireless Extenders, that plug into electrical outlets. Or if you can pull Cat-5e. Add an Access Point.

    No, you don't understand. I have an android smartphone, a W8.1 laptop, a W7 laptop, and they ALL connect to my modem without a trouble, and they all can connect to it from the opposite room of the modem's room. These 3 devices receive the modem sigal more or less with the same strength.

    Now, I have another W8.1 laptop, a Lenovo Y510P, and it can ONLY connects to my modem if I'm in the same room. Everything works fine there.

    BUT if I try to connect to my modem from any other room, the Lenovo Y510P can't connect. It says: "Can't connect to this network".

    So it's not a modem issue, it's my laptop's antenna, drivers or wifi card.

    Nevertheless, I've already rebooted the modem several times, and nothing changes.

    I don't know how to solve it, I've also installed a lot of different versions of WiFi card driver's, and nothing has changed.

    You could try using system restore to go back to the original driver, or at least to before you started trying the different versions.
