I'm running a Linksys WRT54GL router from my CentOS-7 home server. Every now and then (maybe once every 2 days) the router's WiFi cuts out, and I've found no way to solve this except to disconnect the power from the router, wait 10 seconds and then re-connect. This always works. The router is running under dd-wrt. My question is - which makes it a tiny bit CentOS-related - does anyone with such a router know of a way to wake the router up in such a case through the computer? I wouldn't have dared to ask this question here or anywhere until recently, as I assumed my ancient Linksys routers were obsolete. But I've been reading posts recently saying that there hasn't really been a Linux router to replace the WRT54GL, and in particular Linksys's recent 11n replacement is not as good as the old model in many ways. Anyway, if anyone has an answer to my query I should be very grateful. I have a couple of IP cameras working by WiFi on the computer, which I can look at remotely. I've connected one by TP-Link through the router, and this doesn't cut out, but it is not wholly satisfactory. But this shows that the router is alive and well, only its WiFi side is failing. -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

I had an old ASUS router running openwrt which had some issues with its wireless. My workaround was to run a cronjob in router that would do wifi up every hour or so.> I wouldn't have dared to ask this question here or anywhere > until recently, as I assumed my ancient Linksys routers were obsolete. > But I've been reading posts recently saying that > there hasn't really been a Linux router to replace the WRT54GL, > and in particular Linksys's recent 11n replacement > is not as good as the old model in many ways. > > Anyway, if anyone has an answer to my query I should be very grateful. > > I have a couple of IP cameras working by WiFi on the computer, > which I can look at remotely. > I've connected one by TP-Link through the router, > and this doesn't cut out, but it is not wholly satisfactory. > But this shows that the router is alive and well, > only its WiFi side is failing. > > > -- > Timothy Murphy > e-mail: gayleard /at/ eircom.net > School of Mathematics, Trinity College, Dublin 2, Ireland > > > _______________________________________________ > CentOS mailing list > CentOS at centos.org > http://lists.centos.org/mailman/listinfo/centos

I used to run that exact combination, but no longer have one around to look at, so I don't recall any details. or if you can run a cron job on it, you may be able to reboot that way. Also note another poster suggested another way to do it via cron.
