Repeated disconnects

[triphazzard]

I've been experiencing repeated disconnects on various devices for some time now and was hoping that support could take a look at my router ( HG633 ). Examples of disconnects include the following :

• I have a gaming PC and both Steam and TeamSpeak will disconnect simultaneously. TeamSpeak will not reconnect and must be restarted. This used to happen more frequently several times per session until I turned off Attack Protection and ALG. Now it is still common but usually only happens once per session.
• My wife's Dell laptop will disconnect repeatedly throughout the day making it almost unusable if she needs an internet connection.
• My work laptop VPN used to disconnect at least once a day. We've upgraded the VPN from AT&T to Citrix and recently I observed the VPN disconnect and reconnect over a dozen times in one day.
• Our LG Smart TV ( 49UF680V ) will often disconnect from WiFi. Sometimes it can be reconnected, often it won't connect until the router is restarted.
• An NVIDIA Shield occasionally disconnects from WiFi and needs to be manually reconnected. This is running a Plex Server that is available outside of the home network via port-forwarding. This is usually fine as long as the Shield is connected.

Other thoughts and observations...

• We don't tend to notice issues with mobile devices, but that might just be because they can fall back to the mobile network?
• The WiFi network rarely fails completely and disconnects generally seem to affect devices independently of one another. 
• When disconnects happen, the router's lights are all green
• As mentioned above, Attack Protection is disabled as this seems to make the Teamspeak VoIP disconnects much worse. ALG was also disabled in an attempt to make VoIP connections more reliable.
• Both WiFi bands are enabled on the same SSID
• I infrequently use a WiFi analyser to select WiFi channels that aren't busy.

You do not need to be connected to any network to see an AP view, I don't know this analyser, is it under the networks tab? Alternatively, check the developer's website for it.

You have not said which network name (SSID) is yours. Judging by signal strength alone, is it the one called "Trip-and-Tiger"? If so it should not be on channel 4 at all. You can only use channels 1, 6 or 11 as they are classed as the only non-overlapping channels. It is currently interfering with channels 1 & 6 and they are interfering with you as well. You need to move it to channel 6, which looks about the best.

I may have some other recommendations when I see the AP view.

Hi Keith, here are screen shots as requested, I couldn't get an AP view for 2.4GHz as, despite my best efforts, I couldn't convince my wireless adapter to switch to that frequency. Hopefully you can determine the favourable channels from the channel view provided. The other networks in my vicinity are largely clustered together in two channels.

Please can you provide me a set of screenshots from your WiFi analyser, then I can check these for you & advise accordingly? Not knowing which one you are using, please can you get me:-

1. AP View
2. 2.4GHz channels
3. 5GHz channels
4. Signal strength/time graph (let it run for 5 mins before taking the capture)

I will need to know which network(s) are yours.

Please post the screenshots that I have requested in my guide (no photos please they can be difficult to read as text can get out of focus when zoomed in), from the analyser you are using (also in my attached guide). Please ensure that the analyser window is maximised (if Windows) before taking the screenshots & upload them via the "Insert Photos" button (in a mobile browser it's the picture icon) on the post editor's toolbar with the Size parameter set to Large. If they are too small, I will not be able to read them & although I can enlarge them, this puts the text out of focus. If you prefer PM them to me. If you do PM me, then please add a link in there to this thread, so that I can find it easily.
