Dead 2.4Ghz? please post in here

We (dd-wrt community) are trying to nail down this dying 2.4Ghz problem. Trying to, hopefully, narrow it to a revision of the router having the problems. Maybe its a bad batch of routers or something has changed in the routers with that version. we dont know but need your input to gather more info on the problem.

If you are experiencing the dead 2.4 radio problem please post here with:

*Revision of your router (found on the box near the upc, the last 5 digits. ex, mine is 01R13)

*If you have installed dd-wrt on it.

*If the problem appeared before flashing with dd-wrt, or after.


Here is the current spreadsheet for reference: Here

Thanks!

for me it ALWAYS happened on the r15 model. even with stock firmware i have had 3 of them just go out. 2.4 worked and then it just didnt. no reason or anything. since changing them out to r21 i have yet to have any issues with this. and no never even flashed any of the ones that died to ddwrt

For me the R15, was one headache after another. Ethernet port vanished, or would connect at 10M or 100M. The 2.4 radio would disconnect & then reconnect for no apparent reason.

The R17 I have now is OK after about 2 month of constant usage. Both 2.4 & 5 GHz are working without issue.

most of the r15 were rev 3 boards im pretty sure yours has a rev 4 board on the r17 though its been a while since i opened the r17 i know the r18 was a rev 4 board for sure.

Re: Dead 2.4Ghz? please post in here

I got my WNDR3700 a long time ago and threw away the box a long time ago. Is there a way to tell the revision by looking at the router itself?

Re: Dead 2.4Ghz? please post in here

I threw my box out a while ago too, so I had no way of knowing either. But this thread got me interested in knowing what revision my router is, should I ever run into any problems with it. So I removed the feet on the bottom, then I used a T9 Torx driver from Sears #41554 to remove each of the screws including the two in the middle. I then removed the bottom plate and carefully dropped the circuit board into my hand. On the top of the board, by the USB port, there will be some lettering silk screened there which will be what you are looking for. Mine was labeled as follows: FG400-004 RevC3 Dec 1608 2.4 GHz Then also on the other end of the Circuit Board on the right front, you'll see a rectangular section saying MAC with a white sticker near the edge of the board. On the Sticker there are some numbers and it also says Version 0. BTW..... For anyone wanting to add any antennas, there are at least four antenna taps on the circuit board around the large metal shielded section. Smiley Happy -------- At some point, I may just try DD-WRT on this router as I have used it on a Linksys router in the past. I'm just waiting for it to mature a bit for this model first so as to make sure that most of the bugs are out of it before I gamble with this router. Smiley Very Happy

I have a friend to whom I recommended the wndr3700. He received it with 2.4Ghz DOD. He hasn't installed DD-WRT on it, he just RMA-ed it, and got a new one. I don't know what revision he had.

For anyone who is keeping track of this thread (like me) and thinking "What revision is my Router, I have no box" Netgear has replied to my support request..


After 7 days they have told me this..
"Revision number of our devices are intended for internal use only, we don't release this info to customers."

Re: Dead 2.4Ghz? please post in here

correct as i have said. BUT we all do know for a fact they do perform differently depending on the revision number. many people have had issues with r15 and swapped it for r21 and are now happy with the r21 such as myself..

Netgear please pull this off the shelves. The wireless part doesn't work at all. My cousin had same problem. When we called customer care, they very angry and making us hold. Rude on phone to me. Said my computers broken. I wasted my money and time and gas.

The wireless stopped working suddenly

0R17

I am running the latest stock firmware (.68NA). I didn't get to test any other versions really because I updated as soon as I connected the cable modem to it.

Wireless drops, seems like both radios, though I guess I can't be entirely sure. I turned off the 5 GHz radio because people have stated that it helps, and it seemed to, but the connection just dropped again recently. I tried DD-WRT, but I had relatively the same issue.

Just wanted to chime in with my info:

Revision 01R15

I have not yet installed dd-wrt.

I have had this router for 3 months so far. Worked great for the first month, then I noticed I was no longer able to connect in the bedroom where I was previously able to get a strong signal (g and n). This past month have been plagued with constant connectivity problems.

When you say ‘g and n’ do you actually mean the 2.4Ghz and 5GHz bands? If so are the connectivity problems with both bands?

Re: Dead 2.4Ghz? please post in here

R18 running the latest firmware (1.0.4.68NA). Running flawlessly since June 13th. As of September 9th, my connection to a WN311B adapter and Motorola Droid has suddenly become VERY unstable. Connection speed is bouncing off the walls...back and forth between 0, 8, 60 and 130Mbps with random disconnects from the Internet.

I would also like to mention the problem/symptoms are identical to what I experienced when I was running an older WNR834B router. IDENTICAL. My theory is that it's faulty firmware and it has something to do with being unable to auto select the correct channel in the presence of interference from neighboring wireless networks and/or the combination of n and g hardware running on the same wireless network. If it were faulty hardware, why would a factory reset or firmware update temporarily fix the problem?

In the modem settings, I switched to 300Mbps on the 2.4Ghz network, which forced a reset, and then switched back to 130Mbps which forced another reset. This seems to have remedied the problem. Please report back to me if you have any success doing this.

My next troubleshooting step will be to move my PC to the 5Ghz network so that my G and N devices are no longer connected to the same network. This was my plan from the very beginning anyways.

I really really realllllly don't want to RMA this thing for the R21. Why can't it just work without any troubleshooting?

Re: Dead 2.4Ghz? please post in here

I came here looking for help for this exact problem. My 2.4ghz signal just died suddenly, and the 5ghz signal has become so weak, we can only get a connection while in the same room. I'm running the latest firmware but the problem happened before I updated. Have done a reset to all defaults, but still the same problem. Can I downgrade the firmware?

- Rev 01R10
- had DD-WRT installed, device worked fine for some 5 to 6 weeks
- 2.4 GHz gone suddenly completely dead with no apparent cause
- 5.0GHz is since so weak that it is unusable
- I then loaded stock FW 1.0.4.68, no change in the WLAN
- I then tried all former stock FW versions, also no change

Re: Dead 2.4Ghz? please post in here

Looks like its a hardware issue. I would advise you to just RMA the router, no other option really. Dont bother with support as they will only blame you for the problem and it cannot be fixed through any software. It happens on dd-wrt, stock, and openWrt. So, if anyone else has this problem report it in this thread and then RMA the router. We would appreciate hearing from you so that we can track the problem routers.

I've got the same problem on a WNDR3700 I bought in may.
I mean, I still can see the wireless access point if I get close enough to the router (less than 30 cm), but the rate is then 2Mb, no more....and if I move away from the router for more than 1m, the signal disappears...

01R17 Bought about a month ago. Wireless quit working a week ago.

I cant sit and wait for them to replace. Anyone know if they will give credit. With a problem this widespread, it looks like they would want to take care of any issues immediately.

1st unit purchased Sept 29 was dead on arrival, unable to connect to internet. 2nd one was working until last night when I suddently lost all wireless. All troubleshooting failed. At least I can still hook up to the internet?!

Latest firmware installed
Build: 02R1

Im quickly losing confidence in netgear routers.

Re: Dead 2.4Ghz? please post in here

Whenever I purchase a new router, I do a 24 hour "burn in" test doing a bi-directional transfer and look at the transfer graph the next day to see disconnects/discrepancies.. If their are some, it simply may be interference but I do another 24 hour burn in test to see if discrepancies still exist. I do it on both bands. Quite a few routers will overheat or simply fried themselves out. When such a router past such a "torture" test they'll last for years & years before becoming obsolete Smiley Tongue Many routers will return to their normal states after you let it sit for awhile to cool down, but some just gets damaged. Most have 30+ days return policy, so it should be fairly easy to do.
