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 have to say that though I hear other people speak of their routers needing frequent rebooting, I've never had such a problem, though I have to admit that I've only ever owned two routers.
The first of th em was a WRT54GL, and it ran fine. It would run for months, and only get rebooted after a power failure, or when changing things in its UI that required it reboot. I ran the factory firmware for a year or two then switched over to DD-WRT, and again never saw that kind of problem.
Just wondering if you've ever done a firmware update? sometimes even the manufacturer will issue a bug fix firmware update, shocking as that may seem! :)
After five or six years, it suddenly decided it didn't want to retain any of my settings across a reboot, and it was a huge pain to reset all the settings I had made, without notice, whenever it decided to drop them all. So I bought an ASUS RT-N16 and put the Linksys aside for a while.
Subsequently, someone else I knew needed a router for guest network access, and I fired up the WRT54GL and reinstalled latest Linksys firmware and it has been running fine ever since (couple of years, more or less).
Wish I could offer some actual help! :)
