Purchased new router. One of four devices cannot connect to internet


Go to solution Solved by LostCat,

Question

KKoo

I purchased a Netgear Nighthawk 1900 router.  One laptop, one tablet, one mobile phone all connect fine and are online

 

One laptop obtains an IP from the DHCP but cannot connect online

 

If I tether my phone and create a Wi-Fi hotspot, this laptop can connect to the internet.  It just doesn't play nice with the new router for some reason.  It also connected to the internet fine using my old wireless router

 

I've tried ipconfig/release and renew.  No change

In the IPv4 properties, both IP and DNS are set to Obtain Automatically

 

When I ping www.google.com, I get one or two responses and the other two/three time out.  The initial website I enter in the internet browser will work if I wait long enough (about 3 minutes).  Every subsequent attempt fails

 

Have tried rebooting all devices

 

Any help would be appreciated.  Thanks

I would definitely upgrade the firmware on the router if there's one available (no matter how new it is, you can guarantee it has firmware updates) and the network drivers on all the clients.

 

Default Windows drivers and even plenty of laptop manufacturer provided drivers have been quite ###### over the years.

Did you update the router?  This is a common issue on early release firmware.  Also might want to check the encryption type.  It is likely that the old router used TKIP instead of AES or vice versa.

Make sure you use default channels for your region. Some old devices only work at 54Mbps.

The laptop with the issues is about 2-3 years old.  The wireless card per Device Manager supports 802.11n.  54Mbps is 802.11b I believe? 

 

I'll try to drop my Wi-Fi down to 802.11b and see what happens

Do you mean specifically to the Netgear Nighthawk?  Yes, I upgraded the stock firmware the moment I could.  I'll try to change the encryption and see what happens

Is it one of those Intel Pro Wireless adapters? I've seen compatibility issues with them.. they are horrible.

I've seen it on quite a few routers with the firmware out of the box.  Either way I don't think it is with that router being so new.  Its likely an encryption issue.

UPDATE:

 

Dropping the mode from 600 Mbps to 54 Mbps per Riva's suggestion worked!!

 

Not sure what the implications are (I believe this is 802.11b? so I'm guessing slower speeds all around?)

54 is G.  N is 300.  Not sure how they qualify 600, though it's still N.

It's 802.11g. You are restricting all of the decides on the network to 54mbps. I would get a n adapter rather than run g on your network.

SECOND UPDATE:

 

As you guys suggested, I really didn't want to limit my network to 802.11g

 

I used the Windows update to try to upgrade the laptop's network adapter drivers but Windows couldn't find anything.  I then went to the manufacturer's (Broadcom) website and downloaded new drivers (released in 2014 vs the 2013 one I was running).

 

Now the laptop supports 802.11n (which it should have all along, given the "802.11n" in its name) and so does the rest of my devices.  Thank you all for the help!!

 

PS:  Regarding the 600Mbps, I believe it is new technology in the Netgear Nighthawk and Asus RT-AC68U routers.  There is something new in the processor of these routers that enable them to push beyond the previous 802.11n thresholds (per watching Youtube reviews lol)

You just gotta have it on "auto" instead of 80 or 40 or 20 Mhz manual channel width

...and you bought an 802.11AC router why ?

Yep what's the point if you gotta force to 54mbps... might as well pick a 54WRTG at goodwill for 2 dollars!

I was able to upgrade drivers and get all of my devices on 802.11N now

 

Got the router because it was on sale and I was upgrading from a WRT54 (running Tomato firmware) actually

 

Future device purchases will likely all support AC so picked up the AC router

What's the exact model of your Ethernet card as it appears in device manager?

I don't remember it exactly, but Broadcom 802.11N network adapter

 

I installed new drivers from the manufacturer's website and everything is fine now :)  Thanks

Thats cool - Now that you have all the devices connected, time to start messing around with the settings -

Remember the Golden Rule:  Fix it till it breaks !

These new high end routers are dual band...so OP can have a 2.4 GHz network and a 5 GHz network. I also have a newish AC router with dual band - I have a 2.4 GHz  network + a 5 GHz network. The 2.4 GHz network is for the two older devices I have, and also for my friends.

I got dual band too:

 

My Network hardware: Cisco Meraki Z1 router, 2 x Aruba RAP 109 APs, 1 Cisco Meraki MR12 AP. D-Link DGS-1210-10P PoE managed switch.

I have read where many of these new AC routers have issues with the non-AC connections.  Reports of dropped connections and overall poor performance.

Can anyone comment on this ?  Had any bad experiences ?  It was on the WRT1900AC from Linksys (Belkin) mainly.  I know that router is not considered to be very good overall, but was wondering if any other AC routers were experiencing any issues.

a lot stems from 80mhz forced mode. if you leave it in auto it will work.

I have a TP-Link Archer C7. I live in a small apartment (~850 sq. ft, 1 floor). My previous router was a D-Link DIR 655 (802.11n) that was in a ~1800 sq. ft house, and that got excellent signal everywhere. I can't really comment on the range of the new router since I live in a small apartment, but I do get perfect signal everywhere. Like I mentioned in my previous post, I have a 2.4 GHz network setup (iPod Touch and Chromecast are on this network), and everything else is on the 5 GHz network. I have had zero dropouts, and connections have been rock solid. I'm thoroughly impressed with the router, got it on Black Friday sale for $50. I think it's one of the cheapest AC router that has fairly decent reviews. Not sure about the Linksys/Belkin AC routers - I don't have any experience with them. I was thinking about some either picking up something in the Netgear series (Nighthawk) or something like the Asus RT-AC66U, but both are pricey. 

 

I also love the fact that no one else has a router near me on the 5 GHz spectrum. The 2.4 GHz frequency here is pretty populated, roughly 15 networks in my WiFi scan.

The 5ghz doesn't penetrate as far as the 2.4. So you may have some near you but not near enough to interfere.

The newer British Telecom router has dual band but some devices have issues connecting the work round suggested is to separate them using the menu option and name the two bands differently.

I have the Buffalo Extreme AC 1750 Dual Band router at home and at work for over a year and have had no issues. My wife's old ipod and my TV connect on the 2.4 Ghz band my Note II connects to the 5Ghz band. I have never perceived any negative issues on any of them. Hell, my Dad, who lives next door to me connects his laptop to the 2.4 Ghz from time to time with no issues. He's about 200 feet away.

First off, sorry but advice to drop to 54 is not the correct answer, and should not be marked as such.  And without some details was just bad advice all the way around.

 

Clearly the laptop was connecting - just seemed to have issues since it was seeing packet loss

 

The .OP has given no details at all to the configuration, other than he mentions 600N - what was encryption set too?  wpa, wpa2, tkip/aes? 2.4 or 5?  It is not possible to be set for 600 without 40mhz channels and low guard rate so would only be option in 5ghz.  And you have to use 4 spatial streams to achieve it - so in other words never going to happen since what client has 4x4?  Even if the router has 8x8 ;)

 

As to the 600 being something new in the nighthawk - no its not new its just router that 4x4 spatial streams and would even be able to support the mode - problem is there are no 4x4 clients, etc.. So its just pure nonsense..  If you want to get those sorts of data rates you have to go AC. But it seems the OP has no AC devices anyway.

 

So the answer that should be marked is the getting new driver, if he made no other changes to wifi settings - but without wifi settings and devices in use this whole thread is just a waste of anyone's time that stumbles across it trying to find answer.  I highly doubt driver added N support.  But it might of fixed a bug is more like like it.

 

So OP what are you settings now, are your devices even 5ghz?  To get more than 54 data rate in N you also have to be using WPA2 or OPEN..  Many cards adhere to this.  - but without details, what card you have - what wifi settings you have this thread is just going around in circles with the likely hood of more and more fud to be posted.

 

For example that AC routers have issues with N connections - where would anyone ever read such nonsense?

Yes, you are correct.  I have marked "updating drivers" as the correct response

 

I have two Android devices running on 802.11n 5ghz.  2 laptops running 802.11n on 2.4ghz.  I hope to get a new smartphone sometime in the future that supports AC

 

Re. the laptop that had the issue originally, I do believe the driver update fixed a bug.  Updating the driver immediately fixed the issue
