My ISP is Voyager, I use a Zyxel VMG8324-B10a Router which hosts my VDSL connection.

I use a desktop which connects via ethernet cable to my router - no problems with connectivity

I use a laptop, 2x phones, 1x tablet and sometimes PS3 which connects via wifi. I noticed when using my laptop - it seems to drop Internet connectivity for 2 minutes or so, then connects - this happens intermittently throughout usage (quite frequently)

There are 8+ or so other wifi networks in the area (I can see when connecting from a wifi device). Could the dropouts be due to channels crossing over or interference on my channel etc...

Just wondering if anyone else has this issue or has resolved this?

WiFi on those Zyxel devices isn't particularly great. Changing the channel is the first thing you could look at.

Also ensure it's set to 20Mhz, and not 40Mhz.

Channel is set to AUTO - currently on 13

Was set to 40MHZ in both bands

Do I set this to 20MHZ in both bands or 20MHZ in 2GHZ & 40MHZ in 5GHZ

You can easily use 40Mhz at 5Ghz. 40Mhz in 2.4Ghz is problematic due to the heavy congestion in this band.

Is your problem that your router is selecting ch 13? A huge number of devices incl laptops and phones do not support this channel.

I was thinking of setting it manually maybe? When I login to the Router Control Panel it says set to Auto but channel 13 is selected.

I was thinking of running a Wifi Analyser to check neighboring wifi networks and then move the channel of Wifi to a not so populated one? would this be useful.

Changing my modem to 20HZ now.

I have changed my Wireless to 20Mhz in 2.4Ghz and 40Mhz in 5Ghz - the mode auto selected channel 2

Will these have any bandwidth effects for wifi devices, like decreased speed etc.. I run a speedtest.net from my wifi device and got Ping 14ms / Down: 13.41Mbps / Up: 6.27mbps
Although I am only on VDSL with Voyager.

There isn't an answer to that.  20Mhz will theoretically halve the maximum throughout of 2.4Ghz, but as the 2.4Ghz band is so heavily congested running at 40Mhz can often deliver better speeds and reliability.

Cordless phones can interfere with wireless.

timmmay: Cordless phones can interfere with wireless.


They can, but there are fewer and fewer 2.4Ghz cordless phones around these days. Uniden were pretty much the only manufacturer who sold them in the NZ market, and most are so old now that they're on their last legs.

Bluetooth and microwave ovens are two of the worse causes of interference.

My cordless phone sits next to my router and the router is on the bench under my microwave :D Maybe it's time to consider moving it? My phone is a Uniden Digital

Is it a 2.4Ghz cordless phone or a DECT one?
