Re: How long do Linksys routers last?

Thanks. I hope I did the 30-30-30 correctly since I counted with my mouth.

Yeah, I couldn't find the DHCP times in 192.168.1.1 web pages. Oh well, I guess I will have to live with the problem if it still exists or get a new one. I noticed the rare disconnections are two seconds long and some of my WAN connections do not get dropped like my SSH. Although IM and IRC connections do get dropped so it's not too bad.

I should try power cycling my cable modem too. I will do that if the problem returns. I want to narrow down things first.
30-30-30 method did not fix the problem since it didn't last four days:

[2012-12-02 18:01:36] r8169 0000:04:00.0: eth0: link up
[2012-12-06 08:12:52] r8169 0000:04:00.0: eth0: link down
[2012-12-06 08:12:54] r8169 0000:04:00.0: eth0: link up

Tomorrow/Later this weekend, I will try power cycling my old cable modem next to see if it makes any differences. I doubt it.

It happened again this morning after I power cycled on 12/6/2012 evening PST. I give up. I guess a new router is needed if this gets any worse.

I think it is time to buy a new one...

Uh oh. I just had a major lag tonight on my LAN. My router didn't respond back to my pings either. I think my router is getting worse so I better start looking for a new one. It looks like there is a post-Christmas sale. Any suggestions on what to get for cheap for a small house and that work well for hardwired (giga speed), wireless, and have third party firmware support from »www.salescircular.com/ca/compute···np.shtml list?

Thank you in advance.

8 years strong

8 years for the WRT54G/L version 4 still going strong, rock solid, always running stock firmware, never rebooted, never drop connection. Only time was rebooted when lost power or ISP had outages.

Same for the Motorola SB5100 series 8 years of service, rock solid. I just replaced the Motorola with the SB6121 and so far has been great. Cheers

Need to mention I setup a Netgear GS105 switch between the SB6121 and Linksys WRT54G as SB6121 is 1Gbps only and can't talk to Linksys 10/100Mbps.

SB6121 is capable of 10/100/1G, see this link.

That's correct, the SB6121 is backwards supportive of 10/100 switches and routers and computers. I have this exact modem and switch between an E1200 and EA4500 sometimes, all without a hiccup.

You guys are right. I removed the Netgear switch and the SB6121 and Linksys can talk to each other Thanks much for the info.

Re: How long do Linksys routers last?

I've had my WRT54GS since 2003. Ran Sveasoft firmware for several years before switching to Tomato about four years ago. I have dirty power, but a UPS for the router (in a closet with only the modem) helped out. For the most part this router has been rock solid.

That said, I've just replaced it this week with an ASUS router (Tomato again) due to instability with wireless connections. It seems that too many wireless clients were causing hangs/reboots on the trusty old Linksys. It has been re-purposed as an AP.

Is the activity light on the SB6121 blue or amber? I think the display is the same for the SB6121 and SB6141. If I connect the SB6141, that Oceanic TWC gave me recently when I upgraded to 20/2 and a DOCSIS 3 modem, directly to either my new Win 8 computer, or my old XP computer, the link/activity light is blue (hi speed gigabit ethernet). If I connect my over 9 years old Linksy BEFSR41 then the modem link/activity light is amber (ethernet or Fast ethernet).

Fixed it?

Weird. I wonder if I fixed it? It has been almost two weeks since I upgraded my 24/7 Debian stable's Kernel v2.6.23-5 to v3.2.0 from its stable backport and switching to KDE v4.4.5 (was using Gnome v2.3). I noticed no more disconnections, reboots, etc. on my router. I don't see how that can cause my router to misbehave that way if it is caused by it.

One possibility might be that the OS upgrade fixed a NIC driver problem that was intermittently causing a flood between the NIC and the router's LAN interface. The router might have been rebooting because of an overflow condition, or because it detected the flood and rebooted in order to reset the LAN interface. A more advanced switch would have likely just masked off the offending switch port, but an inexpensive comsumer/soho grade router would not likely have that capability.

Intereting. It could be. What type of floods though? My box can be idling (not asleep/stand by) with no manual network activities.

A flood caused by a hardware or driver failure. The PC does not have to do anything but be physically connected and operational. In the old days of coax ethernet or simple hubs, I have seen that problem drop large LANS to their knees.

The kind of flooding I am talking about usually happens below the TCPIP layer at the ethernet layer, and it would not be visible to iptables in your PC because it occurs inside the NIC and is simply not visible at all inside the PC. Typically with such a failure the NIC just sends a constant stream of garbage bits out the interface and overwhelms whatever it is connected to. Sometimes just disconnecting the interface (as would happen if the router rebooted) will cause the defective interface to reset, and everything works again (until the next failure). I am not saying this is what happened in your case, but it might explain why the problem seems to have disappeared after you upgraded your OS.

I spoke too soon again since it happened at about 8:48:57 AM PST for about a second. Now, I have a suspicion on my Debian/Linux's arpwatch process might be causing it but it just monitors? I noticed that it wasn't running a night ago so I manually started it, and my router rebooted again this morning.

Arpwatch maintains a database of Ethernet MAC addresses seen on the

flip-flops, changed and re-used old addresses.

Or maybe just a coincident? I will keep this daemon running a few more days to see more reboots, and then turn it off to see if it still reboots.

1/16/2013: I saw another reboot this morning. For now, I disabled arpwatchd service to see if the problem returns again. To be continued...

1/18/2013: It happened again and with arpwatch disabled.
