Hi,
I'm running into issues using USB3 flash drives with my WRT1900ACSv2. As soon as I connect a USB 3 drive to the router's USB3 port wifi stops working. After removing the drive wifi comes back. This only affects 2.4GHz radio. 5GHz remains available. Connecting a USB2 drive to the same port does not influence wifi functionality. I'm running LEDE 17.01.2. Any suggestion?
Regards
Wolfgang
This... actually sounds like interference. Read:
Thanks for pointing me to this information. I wasn't aware of this kind of interference. It surprises me that even if there is interference tools line Wifi Analyzer do not show the slightest trace of a signal while being just 50cm away from the router's antenna.
Yeah I don't have much advice to mitigate this. You could try wrapping the flash drive and the side of the port with aluminium foil. The router probably lacks the necessary shielding on the port. Could also be true of the flash drive.
I connected the USB3 drive to the USB2 forcing it down to USB2. Since it's only used to stream audio media files the lower performance is not an issue. And this configuration works.
Again thanks for you advice!
Same problem also with wrt1200ac!
If I connect hard disk or pen drive usb 3.0 wifi 2.4GHz stop working.
Tested on LEDE 17.01.2
Is certainly a bug, can you change the title of the discussion?
this is a hardware limitation, not a bug.
After trying this on the stock firmware with the same hardware, I see that this is not an apparent hardware issue. 2.4 GHz network appears clearly 3 meters away while transferring files. I think this might be an issue with LEDE. I'm planning on switching to LEDE firmware soon so I'll retry and tell you if it keeps happening. I don't really mind losing USB 3.0 because I have a dedicated NAS anyways.
Hi there, glad to hear that someone tested this on a stock firmware. I wanted to ask the very same question after reading the post from craz. So I also think that this is not a hardware but a software issue with LEDE.
I confim no problem with stock Linksys firmware also for wrt1200ac
Did someone check the system log after booting?
This week I'm not home to check
I have a wrt1200ac running LEDE David's build without issue on USB3 HDD and 2.4 wifi at the same time.

[ 17.957220] IPv6: ADDRCONF(NETDEV_CHANGE): eth1: link becomes readyToday I tried the last snapshot (r4831) but the problem is always present.
I have also changed hard drives but if I connect it to usb port 3 wifi 2.4 GHz doesn't work.
Incredible!
What happens if you use a usb2.0 enclosure?
Don´t change the Drive itself -> try different enclosures (if possible)
I´am able to conntect diffrent drives (SSD/HDD) onto diffrent routers....
With USB 2.0 enclosure all is perfect 
Or just change the cable to standard microusb.
@wkorn
Did you still have this issue? If yes can you try to boot the device without the USB3 HDD and them plug it?
Once I noticed this issue I already tried booting without the flashdrive and connecting it once the device was up and running. Wifi was working and immediately after connecting the drive to the router the 2.4GHz network disappeared. Since I didn't change anything the problem still persists.
