Wi-Fi disappears in TP-Link TL-WR841ND (dd-wrt)

Question

WiFi

There is TP-Link TL-WR841ND v7 . It has DD-WRT v24-sp2 (11/21/10) std - build 15778 on it .
The last 2 weeks, constantly, after some time (several hours after launch), the signal from Wi-Fi disappears.
Wireless settings:

Wireless Mode: AP
Wireless Network Mode: N-Only
Channel Width: Full
Wireless Channel: Auto
Wireless SSID Broadcast: Enable
Security Mode: WPA2 Personal
WPA Algorithms: AES
WPA Shared Key: [Latin mixed case letters and numbers, 16 characters]

When the wireless connection is lost, the wire continues to work.
How can it be cured?
Thank you.

Answer 1

I will share my experience.
With the new DDwrt firmware, my dlink320 router is very "overclocked" in terms of throughput. But it also increased the load on the processor. And at the moments of downloading especially seeded distributions or even from the local FTP, he simply “choked” and fell off either the wylf, or the webmord, or even the router itself would freeze. Cured by a simple speed limit to 4.5 MB per second. Perhaps you have something similar?

Answer 2

Such problems often occur due to the "drying" of electrolytic capacitors in the router / modem power circuit. These can be capacitors, both directly on the router / modem board, and in an external power supply. It is treated by replacing the capacitors.

Answer 3

about! I had this symptom too. First flashed on openwrt. Helped.
Then a friend urgently needed a router with a configured 3G modem.
I bought myself a new one, did not begin to flash. And so everything is fine.

Answer 4

Faced a similar problem. Some time ago, the TP-Link TL-WA901ND v1 point periodically stopped letting me into the network: there was a signal, but I couldn’t connect. In this case, the point is available through the wire. Reboots didn't solve the problem. Then I noticed that there were multicast addresses in the connection table. I remembered that just a couple of days ago I set up igmpproxy for IPTV. Turned it off and oh cthulhu! the laptop is connected to the network.

Answer 5

Firmware: DD-WRT v24-sp2 (03/24/10) std TP-Link TL-WR1043ND The wafer also fell off about once a day. Poshamanil several times the settings began to fall off every few days

Answer 6

Also periodically there are problems with wifi. Once it was due to the fact that one laptop on Linux littered the network. Yes, it happens. It turned out that there is a card with crooked drivers. I had to buy an external whistle.
Also, there was a problem with the poppy. The Internet suddenly became very buggy. Disabling n mode in the router helped. The Mac connected through it. I put only g, it became OK.
Recently, too, began to fail wifi. Changing the channel helped. See which channels are the most free. You can use the program for Android - Wi-fi Analyzer.

Answer 7

There were glitches with tp-link 841, I tried several third-party firmware. As a result, I rolled back to the factory firmware, only a couple of releases lower. The glitch didn't show up anymore.
