Why do I have to reboot the WRT54G3G-ST 2-3 times a day?

I know about rebooting the router through the browser interface, but often that just does not work and actually unplugging the router is the only way.

I have noticed that I have to reboot very infrequently now since I started unplugging the router at night when I'm done. I also shut down my computer each night, then in the morning reboot the computer and then, when it's completely up and running, plug back in the router. Since I've started doing that each night, I am good to go all day without a reboot.

The last post may have a clue in it. Most of the prior posts say they rebooted the router or turned it off, etc. and still had problems. None said that they shut down the computer.

Based on my experience with a router and Comcast, the proper method was to shute EVERYTHING off, wait a minute or two then turn on the modem, wait a bit, then the router, wait a bit, then each computer.

So add shut down the computer and turn off the Linksys and wait a bit. then turn on the router and wait a bit and then turn on the computer.

My ancient experience with modems indicated they could store bad init strings and corruption in memory and the modem itself had to be turned off to clear this out. Perhaps the computers are also storing a corrupted bit of data for the modem/router.

This doesn't deal with the issue of why it is shutting down but may be a better way to recover. THe broswer method may also be better.

I think I've finally found my problem w/my router & the PX-500. It was basically a problem w/the Wifi piece of the Linksys and not the broadband card. This is what I noticed...

I would have intermittent problems w/the internet even after rebooting the router. Going to the management console of the router always worked (wirelessly), but internet wouldn't sometimes. Well I finally plugged a network cable from my laptop to the router and bingo the internet worked (w/o reboot). I also notice alot of other people around my home running wifi. So I'm guessing that my router and the other routers are interfering w/each other. I basically changed 2 setting. I enable broadcasting SSID (which I previously disabled) and I changed my channel to 8 versus the default 6. So far I've been running fine without any required reboots of the router.

Also if anyone want to automate the rebooting of the router, you can use a program like curl to simulate clicking the reboot button on a dos command line and schedule it. (Logging in to the GUI and clicking the reboot button is the only other way I know of doing it). I've got this command in a batch file.

curl.exe -u "admin:passwd" -d "submit_button=Diagnostics&change_action=&action=Reboot&wait_time=28" 192.168.1.1/apply.cgi

I think I found something that fixes the reboot issues...

I was running into the same thing, everything would look like it was passing traffic, but it wasn't.

Well on a whim, I disabled the wireless from the 3g3 and connected a wrt54g with DD-WRT firmware. SUPRISE! No reboots! So, I am guessing that Linksys did something bad in this version of the firmware to the point that the wireless loses its mind enough to no longer connect to the net.

I am going to play with this a bit more next week, but it sure is interesting.

Didn't someone say that they had a version of DD-WRT for the 3g3?

Furgus,

I would love to use curl the way you explained it. I just don't know how to use your command line in a batch file?

Beside my specific question above. Has anybody who had this loosing Internet connecton with the Linksys actually solved that issue?

I was on the helpline with Linksys twice and did as they recommended: Latest firmware (again), 30 sec reset + 10 sec power off, and reduced MTU to 1400. Did not work. After a couple of minutes - sometimes more, soemtimes less - I loose Internet connection despite the fact that the router still reports "connected" and connection as "excellent", the blue Internet LED is still on and the Sprint card (S720) is still falshing green. Only a reboot helps, for another couple of minutes.

I guess I have to throw that Linksys away and accept that is simply a ridiculously immature product if one looks for a steady Internet connetcion. Has anybody any practical experience with the K1 router or any other working router for a S720 card? I am also thinking of (mis-) using one of my notebooks as a permanent "Ineternet modem" as the connection seems to be stable there - anyone done this?

Thanks!

Since my post of Apr 9, 2007 under this topic, detailing my problem with losing Internet connectivity, the problem is gone.

After about a month of having the stated problem, it went away. I don't have to reboot the router anymore. I haven't changed any hardware, settings, or anything at all. I never called Sprint to report the problem. It just went away. Sure hope things stay this way!

So, I believe the cause must have been on Sprint's end and they did something which fixed things.

it's odd...I've had my router since Feb and outside of the upload issue, I haven't had any problems. I took the router to vegas with me about 10 days ago, and had to reboot the darn thing at least once a day. I've never had that problem at all here, I just totally loose internet connection, even though the router said I was still connected, I tried disconnecting and re-connecting..no difference.

I have a PX500 card and also noticed that it would cut out without the blue light on the wrt54g3g-st going out. This happened several times during the day, and I would have to push the "Data Card" button once to turn off the blue light and then once again for the card to log in again. This worked and I had internet access again. My suspicion was that the connection to the Sprint network timed out after inactivity, regardless of what the routed indicated. To test this I started to have my Outlook email app check for new mail more often. Originally it was checking every 10 minutes. I changed it to four minutes and that did the trick. When I came into the office this morning, the connection was still active and working. ( I leave my system on 24/7).
Please someone else try this approach of creating activity on the connection to keep it from disconnecting and let me know how it works!!

Well, I'm having the exact same problems as all of you with the Linksys WRT54G3G-ST and Merlin S720 card on Sprint.

First two weeks were heaven, I think I left it all running pretty much 24/7. Last week, I may have had to reboot the router once a day. Now, it's pretty much unstable...it might work fine for an hour or two, or lose connectivity every 15 minutes and require a reboot.

This needs to get solved ASAP. Following along on what's been said here, I lowered the MTU value to 996 and set my Outlook to check email every 4 minutes. Will keep you updated.

The fact that the problem doesn't onset immediately with a new router but takes a week or two must be a key or informative piece of the puzzle.

you may want to take your broadband card out and leave it in your laptop for several hours (let it connect) so that it can get any updates it may need.

I was experiencing the same problems as you guys, and this appeared to solve the issue....then too, I completely reset the router (as in wiped its setting and re-entered it).

My problem, right now, is that I suspect the radio unit is going out; before all the WiFi channels allowed me to have good download speeds; not only the high channels let me; either way, a replacement is on the way; hopefully this will resolve this issue.

I can't wait until new firmware comes out for this thing; hopefully the upload and stability issues will be solved.

Well, I'm still having the same problems today, so neither mucking with the MTU setting or having Outlook maintain a constant connection seem to have solved the problem.

Turning everything off overnight did seem to improve performance for the first four to six hours, but connectivity (er, lack thereof) returned to normal status ante quo.

Removed my S720 card from the Linksys router and ran it in my laptop. Haven't seen any connectivity issues in the last few hours, so it definitely appears connected to the interface b/w the PCMCIA card and the router.

I made a couple changes since I the card in the laptop. I made the card connect to EVDO rev A only, no 1xRTT since I'm in a good signal area (Chicago). Also checked for updates, none, of course.

Well, I'm going to move the card back to the router tonight and see if anything improves. Confused

There are enough people with this problem that Sprint/Novatel/Linksys should get their teams together and solve this major issue once and for all.
