Does anyone have experience with a disappearing wifi access point (AP)?

Is there anything that a cable modem might do to provoke this event?

All is working fine. Workstation wifi activity stops at random intervals. It will return at random intervals. I can power-off restart the AP/router to restart net activities, but it will eventually disappear at a later time.

I've used a wifi analyzer app looking for the AP. It is completely gone and not simply -200 dB or similar.

I've tried to treat it as an AP whose SSID is hidden, but that did not work either.

If this is a hardware or other AP/router issue, I guess that it means I need a replacement. Any suggestions for something to cover a 2600 sq-ft ranch house?

Before you ask, the failing AP/router is a D-Link DIR-655 that has been working well for quite some time. It is connected to a cable modem for internet service.

Thanks in advance,

The wifi went TU on one of my router's many years ago in a similar fashion and a replacement would be my first suggestion. Since you already created a similar thread with a post will have this one closed.

Dan, what's "quite some time"? Routers do seem to wear out after a time...I get around 7-8 years out of them.
I'm currently running a pair of TP-LINK devices. One is router-WAP at one end of the house, the other is a range extender for the far end of the house. (2000 sq.ft. ranch) I won't bother with model numbers -- they're both obsolete -- but they're working fine (so far).

I've mostly used Linksys® until they went screwy (the company not my boxes), then I started using Netgear® because we used that at work and I had knowledge and experience with them. I have NEVER seen an AP/SSID "disappear" and "return" if it was powered on. After all, it is a radio station broadcasting and identification.

In this case, the network (ISP) service entrance is in one corner of the house. The master suite is opposite. Other bedrooms and the kitchen occupy the other corners with the family space in the center. There is no in-wall network wire and no cheap/easy way to add them. I think net-over-powerline (NOPL) might work, but I've never tried to run an AP downline on a NOPL.

The family desktop box is near the service entrance and could connect to the cable modem directly. NOPL to somewhere else to move the AP near the center of the living spaces. A direct connect to the cable box would leave the desktop out of the wifi lan segment so I'd likely need to add wifi parts to it (ugh! winXX). I could also add a second NOPL port. These folks are very light users so they won't require giga-anything.

Thanks in advance,

The first failures I had were with a Linksys router...replaced with Netgear. Then my Linksys AP went south. Again, these were over 7 to 8 year intervals...I've been running an in-home network here forever

I have had good experiences, as I've said, with a router/WAP near the IPS modem and an "wireless range extender" to get to the other end of the house. I'm not sure brand matters that much. I got a good deal on the TP-LINK devices on Amazon, is all.

As I type, there are two wired clients and 13 wireless clients reported by the main router which is also supplying dhcp service.

michaelk: I'll follow in the other thread from now on.

It seems that I had failing hardware.

Thanks for the help,
