I have a curious problem with an old WRT54GL router, which I use as a WiFi access point on my LAN:
Internet->ADSL modem->CentOS-7 computer->WRT54GL router
The router has always had a slight problem of losing connection every so often –
it used to be every couple of days, but recently it has become much more often.
My cure was always to disconnect the power from the router for 10 seconds or so, and then re-connect it.
Recently I discovered that running the following script on the CentOS computer seems to solve the problem (for a while)
sudo systemctl restart dhcpd
sudo systemctl restart network
sudo systemctl restart shorewall
(I suspect the first, dhcpd, is irrelevant.)
Incidentally, I am able to ping laptops on the LAN
(but not the other way round)
even when the router is in its “bad” state.
I wonder if anyone has had a similar experience, and can offer advice?
I don’t like to examine the internals of the router, in case it stops working altogether. I’m planning on getting another router (N protocol), so it is not a very serious matter –
I’m just puzzled by it.
