C3700-100NAS problems after V2.02.06 firmware upgrade
Bought C3700-100NAS few months ago, and it was working perfectly until few weeks ago. Now whenever I have high upload traffic on WiFi (uploading a large file for example or doing backup), WiFi radio ...
Hello dshapovalov
We are looking into this issue if you could provide a little more detail from these questions that would be great
Can you please provide the ‘backup config’ file and the models of the wifi clients that cause the problem? (I will pm you a email to send the Backup file)
will any wifi device cause the issue or only a few?
what type file upload service you used (e.g FTP, dropbox, etc)?
Hope to hear your feedback

Darren, I've send backup config to the e-mail provided.
I only had issues on one device, others have no need to upload large files or do backups, so can't say about those.
The device is laptop Lenovo X250 with Intel(R) Dual Band Wireless-AC 7265 adapter.
I'm just copying large files (few GBs) or doing daily backup (also usually few GBs) from the laptop over WiFi to another computer on the network, which is connected to the modem through the network cable. It kills 5 GHz radio within a minute, 2.4 GHz and Ethernet interface keeps working. If I switch to 2.4 GHz radio and repeat the operation it kills it too, though on 2.4 GHz it takes longer, usually a few minutes. Once radio is down, no devices can connect to WiFi on this frequency until modem is rebooted. It happens sporadically, sometimes it works fine for a few days, sometimes it happens on every backup or file upload. Only started 2-3 weeks ago, before I had no issues like this for months since I bought the modem. Nothin changed on the laptop, wireless adapter drivers are 3 months old.
Hope this helps, please, let me know if I can provide any more information.
Do we know when this FW was released?
I am seeing major wifi performance degredation for about a week now. I was advised by netgear to basically buy some support (as modem is 100 days old) so they wont even touch it.
I have already contacted comcast too, not seeing any issue directly conncted. What I also noticed is that when my modem boots up - it is online then the DS&US flash for approx 1 min then return solid (normally the lights would cycle if there was a successful update?)
When I turn the router of the modem off, the lights flash the same but then cycle to indicate completion?
I have also factory rest the modem several times (push button reset) still seeining issues even with out of the box settings.
I am tempted to go and buy a tp-link router or something to see if it works (leaving c3700 with router mode off)
