wireless printers or older wireless TVs can be causes). If your 802.11AC dongle is on the same frequency as 802.11N, performance will be degraded off the bat so consider moving those devices onto a different frequency if you have a dual-band router (e.g. Can't recall if camping is a problem - I'm less clear about the details here, but it should be. Do you have any old devices on your network? Your WiFi router will run at the speed of the slowest client. That being said, it's a simple thing to try so why not?ĭoes "flaky" here mean connection going in & out vs inconsistent & bad speed?Īssuming we're talking about speed rather than the connection itself, two walls can be a challenge if you're on 5ghz depending on the quality of your router & dongle. shouldn't matter if you are on 5 or 2.4). Unless your dongle vendor did a bad job, USB dongles should be designed to minimize the impact of this interference because all they do is WiFi + USB (i.e. If you're on 5Ghz I've not seen USB2/3 coex be a problem. I'm not aware of USB interfering with anything 2.4Ghz. Please note that interference is generated by both the actual USB 3.0 device as well as its cable." Customers using cellular networks or 2.4GHz WIFI networks near USB 3.0 devices should take measures to reduce the impact of these devices on their network connectivity. This interference can significantly degrade cellular and 2.4GHz WIFI performance. "USB 3.0, or SuperSpeed USB, uses broadband signaling that can interfere with cellular and 2.4GHz WIFI signaling. USB 3.0 Interference - Cradlepoint Knowledgebase See especially Figure 2-2: "the data spectrum is very broadband, ranging from DC to 5 GHz" USB 3.0 Radio Frequency Interference Impact on 2.4 GHz Wireless Devices (by Intel) Started suffering broad spectrum interference that stomped all over L-band (Iridium and GPS) reception. We built a prototype sensor payload that included a USB3 external hard drive. "It's hard not to generate harmful interference." This is woefully understated in the article when it says: I recently learned that USB3 is not only badly designed, flaky and unreliable, it is also an EMI/RFI nightmare.
