Flakey wifi? Router or access points?

RichTJ99 101 10 November 30, 2015 at 02:28 PM
Hi,

I have a Netgear R7000 router running DDWRT. I also have two Engenius ENH210EXT external access points. The access points are set to automatically reboot at 3am.

I have three networks, Test1 (2.4ghz), Test2 (5ghz), Outside (both outside access points share SSID)

I will periodically lose internet access but not wifi. I don’t get a limited connection, its just that the web pages stop loading. I can reboot the three devices (router & 2x outdoor access points) which typically works, or I reboot the router manually. I do not reboot the cable modem.

My wife & kids are constantly complaining that it doesn’t work right.

Any suggestions on what I can do or what I can buy as replacement hardware?

Thanks,
Rich

I would begin by troubleshooting to and only changing one variable at a time and testing. So when there is an outage, can you ping all 3 devices or login?

Unplug one repeater, what happens?
Unplug another, etc.

Basically try and isolate what is going on. Why are the AP's set to reboot automatically? Have they given you issues in the past? I would assume they have some logging capabilities since they are enterprise grade equipment.

I would make sure everything has the latest firmware on it as well.

Hi,

So when it happens I believe I can still ping the routers & access points. It is how I reboot them most of the time. The other night I had an issue, rebooted it via the web admin & it still didnt work right so I manually killed the power on the router & access point.

It worked OK after that. So I can check a later version of the DDWRT firmware.

The AP's are set to auto reboot because I seem to have constant problems (specifically this).

Thanks,
Rich

Make sure to quote people when responding to them so they get notifications of your reply.

I would upgrade the firmware and if still having the issue take the AP's out of the loop. Just unplug them for a day and see what happens.Does the router still work as it should or does it go down too?

Are the AP's wired as their source or a totally wireless repeater? What about the logging on them?

Hi,

I tried a stock firmware upgrade on the unit and am going to see what happens next. The AP's are hard wired to the network.

Thanks,
Rich


I will also try tomato

I would probably recommend the shibby build of Tomato. It's more up to date than the official build which has not been touched for years. https://en.wikipedia.org/wiki/Tomato_(firmware)

What about the logging of the AP? Do you have that enabled/accessible?

Sounds like something is wrong with your router. I would suggest the same and update your router to a new firmware, or different firmware.

Just wondering, why don't you just set up one ssid? 3 sounds like a PITA, and your enterprise access points should hand-off pretty well.

Edit: If you have a spare router laying around it would probably be quickest and easiest to just replace it with that temporarily and see if you are still having the issue.

Keep troubleshooting. You need to determine exactly what is happening when this happens. Is there someone on the network that is hogging tons of bandwidth slowing everything to a crawl, is the network branch you are on malfunctioning, in addition to pinging other devices can you resolve an address via DNS, etc.

Intermittent issues like this can be a real bear to diagnose.

Back in the remote past when I actually went to work each day I recall a similar situation.

After days of pulling hair and beating my head against the wall I discovered that the 12VDC wall wort was losing it's reliable connection to the AC outlet.

I finally decided that this intermittent manifestation was caused by temperature variances in the server room and ultimately the problem was traced to the wall outlet itself. I stopped using that outlet and the problem just disappeared.

If I were you I would not include your access points in your investigation, your router is causing this trouble although the router could affect the access points leaving them in a state that requires restarting them.

If you have a volt/ohm meter I believe you should verify that the router power supply is actually delivering voltage that slightly exceeds the requirements of the router.

Good Luck!

I am still having issues periodically. I am debating using PFSense on one of my older boxes.

Had problems like this before. Router randomly doesn't load websites even though everything was connected properly and I even reset router to default manufacturer settings. New router solved all the issues.

On an x86 box??? Pfsense is great as a router/firewall, but for WiFi stuff it's pretty bad.
