What happens to the router "dies" or "hacks"?

Question

WiFi

I would like to understand what is happening with my router. The Dlink DIR-300 model has been with me since 2008, there were no complaints until Monday of this week (Aug 26). The router is always on.

Setting:
* WPA2+PSK;
* SSID hidden;
* SSID is not a trivial sequence generated by KeePass;
* Internal password changed to 64-character HEX type, again generated in KeePass;

Symptoms:
* WiFi falls off;
* Sometimes it is possible to go through 192.168.0.1 and reboot through the WEB interface;
* If it fails, then turn off 20-30 minutes can recover;

I have access to the Internet "cable to the apartment", you plug in the Internet directly!

There was also an attempt to change the channel, I looked in the inSSIDer program more or less free, but after changing the channel 3 times the situation did not improve

. What else can I see to understand the situation even better? While I think that "dies", but is it?

Answer 1

The only HW problems that come to mind are overheating and capacitors.

Answer 2

These symptoms usually occur for several reasons:
- Power supply, try to replace
- Capacitors, try to disassemble and inspect
- Oddly enough, but the density of networks. Try experimenting with channels
. Well, look at the router logs, if they “hack”, it will be visible there.

Answer 3

I have similar symptoms after heavy torrenting - that is, it is possible that the DIR-300 does not handle large traffic from many clients well. If this is overheating, then intensive cooling will reduce the recovery time and will confirm this cause. Look also in his statistics for the packet counter - maybe someone is really dosing.

Answer 4

Have you looked at the logs?
Possibly spurious traffic from your ISP. Faced very often.

Answer 5

Whichever of the listed reasons (power supply, overheating, conders, interference from neighbors, etc.) is a real source of problems, it's time to change the old man. Better at 5GHz, because it's freer now in it, but we must not forget that customers must also support it.

Answer 6

At one time, because of the buggy native Asus firmware, I crawled to dd-vrt, lived for several years, then crawled back to stock.
now he lives exclusively as a stupid access point, because he gave the routing to a more expensive and smart piece of iron
