Why won’t my Netgear Wifi Adapter connect when using USB 3.0?

I’m using a Netgear wifi adapter, and it’s been properly working for about two years now. I’ve tested it on multiple USB 3s, and it is fully functioning on Windows 10 (even when plugged into a USB 3.0).

But last night I installed Ubuntu 18.04, and it will only work if plugged into a USB 2.0. If plugged into a USB 3.0, it turns on briefly, and then suddenly shuts off.

Other than that it works perfectly fine. Again, to reiterate, it works on Windows 10 when connected to a 3.0 port, works fine on a USB 2.0 port, but will not stay connected if plugged into a 3.0 port on Ubuntu.

Any ideas?

What to do when Netgear router won’t turn on?

The Netgear router not turning on can be quite problematic because it prevents you from accessing the internet. You can use the steps below to troubleshoot your router and resolve the issue:

• Turn off the wireless function and connect your computer to the router.

• Disconnect the router and restart the computer to check the net connection.

• Reboot your Netgear router and modem (if you are using one).

• Contact your internet service provider and check for any network issues.

Intermittent connection issues on Netgear EX6150 Extender in Ubuntu 18.04

I’m having intermittent connection issues involving a Netgear EX6150 AC1200 WiFi Range Extender on Ubuntu 18.04 with my laptop’s Qualcomm Atheros QCA9377 802.11ac wifi modem.

My laptop is generally the only connection on the Extender. My laptop works fine connecting to my other wifi modems, and the connection to my EX6150 extender is generally great, except that about once every hour or three the connection stalls. It seems like the connection is still there to some degree, however, because if I’m downloading something it keeps downloading at a high bitrate, but if I try to load a new webpage, like some google search query, it will stall out and either load the page very slowly or or just stop all together.

The only solution I have found is to restart the connection with:

sudo service network-manager restart 

And that seems to reset everything enough between my laptop and my extender to make things work again. I know some routers get gridlocked with too much traffic sometimes, but since I’m the only one on this extender and I generally don’t seem to have all that many connections to it when it stalls, I’m not sure why there would be gridlock.

Has anyone else ever run into this issue before? Are there other ways to get computers to snap out of it than to simply reconnect?

Ubunti 18.04, Unable to connect to NETGEAR Router WNR2000v3 Admin Page using Wifi

I’m using Ubuntu 18.04 and trying to connect to the Admin page of a NETGEAR Router Model WNR2000v3 using the Wifi. I have spent quite some time researching this online, but have yet to find a solution. Here’s the details:

  • I can connect to the internet using the Wifi, in fact I’m using that very connection to write this question.
  • However I can’t connect to the router Admin page at using the Wifi connection.
  • Ping times out with 100% packet loss, which is weird since I can connect to the internet using the Wifi.
  • I can connect to both the internet and the router Admin page using a cable to the router.
  • If I boot into Windows 7 I can connect to everything using either the cable to the router or WiFi.

I’m thinking that something isn’t configured correctly for the WiFi.

Here is what ifconfig looks like for the WiFi connection:

wlp2s0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500         inet  netmask  broadcast         inet6 fe80::d754:7251:7437:d2f6  prefixlen 64  scopeid 0x20<link>         ether 2c:81:58:fc:12:fb  txqueuelen 1000  (Ethernet)         RX packets 20837  bytes 16304644 (16.3 MB)         RX errors 0  dropped 0  overruns 0  frame 0         TX packets 17315  bytes 2576164 (2.5 MB)         TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0 

/etc/hosts looks like this:   localhost   MyComputerName  # The following lines are desirable for IPv6 capable hosts ::1     ip6-localhost ip6-loopback fe00::0 ip6-localnet ff00::0 ip6-mcastprefix ff02::1 ip6-allnodes ff02::2 ip6-allrouters 

/etc/resolv.conf looks like this:

nameserver options edns0 

/etc/network/interfaces looks like this:

# interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback 

Please let me know if there are other config file I can provide that will lead to a solution.

Thank you.

I have a Netgear R6300v2 router and trying to enable its built in VPN feature

the web gui has instructions of what to do, I followed that closely. however after installing OpenVPN on the clien PC, when connecting I am getting an error: OpenSSL: error:140AB18E:SSL routines:SSL_CTX_use_certificate:ca md too weak MANAGEMENT: Client disconnected Cannot load certificate file client.crt Exiting due to fatal error looking at ca.crt file in config folder, I see that it is using md5 as signature hash algorithm, and I think that is my problem. but the router generates the file .. so is there a way to fix this without replacing the router that would be supported? Thank you gents

Netgear LTE modem blinking green LED

I have the Netgear LB2120 (http://www.downloads.netgear.com/files/GDC/LB2120/LB2120_UM_EN.pdf) modem to try and use cellphone data as internet source. The power led is blinking green when I power on with sim installed.

According to the guide

Blinking green bar. The modem uses mobile data because the wireline connection is down and the modem failed over to the backup Internet connection over the mobile broadband network.

What does this mean? Am I getting internet connectivity or not? I have it connected to a Raspberry Pi and when I ping google.com it doesn’t work.

Use of European Netgear Nighthawk M1 in the US

I’m planning on buying a Netgear Nighthawk M1 for use in the EU but also on holiday in the US.

Now I know there are different frequencies and bands in the US that make it so EU devices cannot work properly or at all in the US.

I have read that some 3G might work however. According to the Dutch Netgear website the device supports the following frequencies:

  • LTE/4G: 700/800/900/1800/2100/2300/2500/2600 MHz
  • 3G: 850/900/1900/2100 MHz

Could any of these frequencies work in the US? I was planning on going for a T-Mobile tourist plan.

Open ports on my NetGear router
