New Network Card Connected to Router, but Not the Internet

by JustSomeNetworkingHelp / June 19, 2017 8:37 AM PDT

I was using an Edimax USB network card until I decided I would prefer something a little more reliable. I purchased a Rosewill N300 Wireless N PCI-E Adapter RNX-N250PCe from Amazon (using my sister's account, since she is the one with Prime shipping). I was not notified that it was shipped (early, actually), and the package was rained on and left in the sun for a day or two. However, it was a large box with a lot of plastic inside, so I decided to try out the card anyway.

After installing it (leaving it a day or two to make sure it was in no way wet), I have found that it will connect to my router (Arris DG860) and briefly to the Internet, but loses the Internet connection almost immediately (long enough for me to reach beta.speedtest.net, but not long enough to even register anything higher than 0.00 Mbps on the test). After losing the Internet connection, it claims to be connected to my network with no Internet connection. I cannot connect to http://192.168.0.1 while using this new network card, either. I've updated the driver with the most recent version. Is there any way that this is a software issue, or will I have to return it as a hardware issue?

Does the old USB WiFi work still?

Yes, the old USB card still works
by JustSomeNetworkingHelp / June 19, 2017 9:11 AM PDT

I am using Windows 10, but in the many reviews I have seen I haven't seen any complaints about Windows 10. I actually have both connected right now, but I disable one to try out the other. So you think it is dead?

Both connected?
by R. Proffitt Forum moderator / June 19, 2017 10:13 AM PDT

Then I expect trouble. When I test such things I use one at a time. Disable may or may not work for reasons I won't carry on about.

Sorry, I mean this is what I'm doing now

All of the testing was done with only the new network card connected. I have since connected the old card and disabled the new one, so that I can access the Internet and ask questions on forums.

A question.

The usual failure I run into is when the owner set the IP addresses in the old card and didn't use DHCP or "Obtain an address automatically."

This can result in what you wrote so far. What is the IP address of this PC when working and not?

192.168.0.3 for the new, 192.168.0.14 for the old

I'm pretty sure I have my settings at Obtain an address automatically, also.

That sounds correct.
by R. Proffitt Forum moderator / June 19, 2017 10:54 AM PDT

At least that's OK.

My thoughts are:
1. It's a bum unit.
2. There are parental or other restrictions turned on at the router. You know this, I can't know this.
3. There is some Windows security software interfering. I've bumped into troubles with almost all of them over the years but when testing I usually boot up a Linux Live USB stick to test hardware with since I rarely want to tinker with an owner's Windows.

Are the antennas on the card?

5. What channel is the card on and how far to the router?

Yes, two antennae

The parental restriction thing is not an issue, thankfully. I have a linux CD that I can test it out on. I will try that.

Works fine in Linux

Thank you for suggesting trying out Linux; I'm not sure why I didn't consider trying that. In Zorin OS, the adapter works fine (I'm using it right now).

So, how do we get it to work in Windows?

something set wrong in encryption of connection

That's what all wifi do when trying to connect, but don't have the proper password entered. It's like any password, both letters, numbers, and case must be correct.

Are both routers connecting on the same band and channel?

Both Routers?
by JustSomeNetworkingHelp / June 19, 2017 12:54 PM PDT

The router and the network card are both on 2.4 GHz, and the router is on channel 1 (I previously tried it while on Channel 8). Not sure how to change the channel on the network card. I know I'm entering my WiFi password in correctly, partially because when I enter it incorrectly Windows immediately tells me.

Some extra info

I'm not sure if this is relevant to the Windows issue, but I am using Bitdefender free antivirus.

Tried Uninstalling Bitdefender
by JustSomeNetworkingHelp / June 19, 2017 12:44 PM PDT

After disabling Bitdefender's protection and changing some options with no change for my internet connection, I decided to try uninstalling Bitdefender completely and turn off all Windows Defender protection. I can access the Internet for about 10 more seconds than previously, but it stops working just the same as before. Any suggestions?

It's sounding more and more like a dead card.
by R. Proffitt Forum moderator / June 19, 2017 1:27 PM PDT

Or zombie. I've yet to disable Defender. Just had to get machines closer to stock.

I can't find where you told what channel the WiFi is on.

Channel 1 is fine.
by R. Proffitt Forum moderator / June 19, 2017 1:31 PM PDT

Was looking to see if it was out at 14.

looks like I'm returning it
by JustSomeNetworkingHelp / June 19, 2017 2:19 PM PDT
In reply to: Channel 1 is fine.

I don't know what else to try. At this point it would be easier to just return it and buy a new (different) one or just make due with what I have
