New Windows 8.1 laptop has very weak connection

rgoo001 · Nov 4, 2014

I just purchased a refurbished Lenovo Y-40 today. It has a dual band wireless-AC 3160 and is sitting right next to my old asus u56e which has "Integrated 802.11 b/g/n or 802.11 b/g Built-in Bluetooth™ V3.0 (Optional) 10/100/1000 Base T".

I pay for 12 mbps internet speed with Time Warner and there are never more than 3 laptops connected to the internet at once.

My router is the motorola SBG6580 and is about 25 ft away in a different bedroom. All my drivers have been updated.

Why is the connection for my Lenovo so much worse?

While using the Asus, I encounter 5 second long lag spikes that reach up to 1000 ping when playing games. Sometimes it happens once every 10 minutes and sometimes it happens every 30 seconds. Is that my routers fault or my Asus? I have not bothered trying with the Lenovo yet because the connection already seems to be much worse browsing the internet and the connection bar in the system tray is always at 1 or 2 bars out of 5.

I bought the new Lenovo in hope that I would be able to avoid network connection problems because assumed it was ultimately faster than my Asus. I still believe it should be and am curious on how to speed things up.

So far, I have updated my drivers, went to device manager/network adapter/Realtek PCIe Family Controller Properties/advanced and changed the "Speed & Duplex" from Auto Negotiation to 100 Mbps Half Duplex. I am not sure if this has helped but I saw it in a similar post.

You need to use two channels with Wireless-n. If your router allows it. Set Channel Bandwidth to 40, Set Channels to 1 & 5, and set just for Wireless-n if no other Wireless-b/g devices in the home.

If the residence is made up of concrete, you may be better off using an external USB Wifi adapter like the Netgear a6200. It allows you to get a better signal than the onboard antennas in the laptop lid.

Thank you very much. I am switching over to 40 bandwith. I am not sure if my router allows for multiple channels. Is there anything here that looks like the right setting?

The 802.11 band has 2.4 or 5,
The 802.11 n-mode has auto or off,
N-support required has off or on,
sideband for control channel has low or upper
control channel has 1 to 7
STBC Tx has auto or on or off

edit: Here are some more possible settings

Also I press apply changes but the bandwith is still saying current: 20

broe23 · Nov 4, 2014

Side Band for Control needs to be Upper, since you have main channel set at "1".

When I switch to 5 ghz, neither of my laptops are able to connect to the internet. Is this normal? It needs to be in 5ghz to select low/upper

Did not tell you to switch the radio to 5ghz. All I can say, if the Gateway does not allow you to make these changes, maybe put in an Access Point in that room if the reception is on the fringe.
