Hello everyone. I'm not sure if I should make this a new topic, but my issue is related to the 5G network on the Rocket modem so here I go.
I have a Rocket modem (CGN3ACSMR, software version 188.8.131.52) and after every power outage the modem doesn't restore the 5 GHz network. To me this seems like a software issue, because when I go into the settings it says that the network is on. Yet the 5G light is off, and no device in my home can see the SSID for the 5 GHz network.
This is not a major issue for me because I can repair it by turning the network off and on again in the settings. I am reporting it in the hopes that somebody in Rogers will verify if this is a global issue, and petition a software patch.
Last week sometime, my 5G network stopped broadcasting. It was working perfectly and it just stopped.
And the light turned out on the front of the modem/router. Rogers tech support had no answer and said I needed to do a factory reset.
But I changed the 'channel' settings for the 5G wifi from 149 (auto), to 149-153-157-161, saved the settings and boom - problem solved.
I figure a neighbour set up their own 5G network and knocked mine out.
So much for "auto" I guess....
This is where an application like inSSIDer comes into play. Load that on a laptop, hopefully dual band and it will display the networks that the laptop can receive in its current location. The linked version below is the last freebie version released. It doesn't show the 802.11ac networks, so the 5 Ghz picture isn't the total network picture, so to speak. There is a newer licenced version out now that does, and which works on a normal 802.11n laptop. it reads the transmit headers and displays the 802.11ac networks that are also up and running. For $20 US, its invaluable for situations such as this.
I have the CGN3AC modem and find the 5G wifi very unreliable, can anyone suggest a fix for this? Thanks in advance
It might be a matter of switching to a channel 149 or higher, as the power output limits for those channels are higher. Then there is the issue of who you're competing with for clear channels.
Here is some food for thought. Load inSSIDer on your laptop, which is a wifi monitoring application. When loaded on a dual band laptop, inSSIDer will monitor both 2.4 and 5 Ghz networks that can be detected by your laptop. Have a look to see what you're competing with in both bands. In a suburban area, the 2.4 Ghz band is usually pretty crowded and tough to work in. Usually the 5 Ghz band is less crowded and easier to find a clear channel. After you have a look at the display, you might be able to determine if there is a a better 5 Ghz channel at or above channel 149. The program link below is for the last freebie version which doesn't process or display 802.11ac networks. A new version is out now that will handle 802.11ac networks in the 5 Ghz band, and which will work on a "normal" 802.11n laptop. The new version will read the broadcast management frames and display the 802.11ac networks that are running in the 5 Ghz band. If you are using 5 Ghz channels, its worth the $20 U.S. to buy, so that you can see a complete picture of the networks that are running nearby.
What you want to see on the graphical display is that your network is the highest network shown, which indicates that it has the highest received power of all the received networks. Generally you want somewhere in the neighborhood of 40 to 45 dBmW separation between your network and any other network that is on the same or overlapping channel. So, while your network should be the tallest on the display, everything else should be well below yours. When that power level separation decreases, you end up with interference and possibly with problems maintaining a wifi network. Your only option is to change to a channel with less overlap from the competition.
Here's the link to Version 4, which is a licenced version.
There is also the issue of what device you are using and how many antenna it has, 1, 2 or more. 1 or 2 is typical. A single antenna wifi system works, but it can be noticeably slow. 2 or more antenna should be the preference. Of course, thats up to the manufacturer to build and the end user to eventually discover when the wifi rates turn out to be something other than what they are expected to be.
Ignite 150u and no 5g
I recently switched from 100u to 150u and now my 5g isn't showing up? Anyone know why?
