Wired devices cannot connect with wireless devices

[Ozule]

Hi,

Hope someone can help me with this issue. Since I changed my ISP I cannot connect wired devices with wireless devices in my home network. I have tried everything, restoring the router, changing some options and nothing...

To give you some examples, I cannot do game streaming on my Xbox One (Wired) to my laptop (wireless), watching a Plex movie from mny laptop (wireless) to my TV (wired) or use Chrome Remote Control from my PC (wired) to my laptop (wireless). I took a look at the logs and when trying for example the game streaming, the router is detecting the connection as a DOS attack. I tried to deactivate de DOS attack protection but still cannot connect.

I know it is not my ISP fault because when using the router from my ISP all work flawleslly. Any ideas?

Thanks a lot

that whole "the router from my isp works flawlessly" seems to indicate that you have it running on the network .

How exactly is your network setup with models/setup.

modem/gateway-------->router----->another router?/switches? 

be specific in what you have setup and running. You could be in a double nat if you have 2 routers running on the same network.

Hi,

I have a ONT then an ethernet from it to the Netgear. I had to set up the VLAN with specific ISP values.

Router: Nighthawk XR500

No additiional routers

1 Switch in the living room.

Cheers

who's your isp and what ont are you using? 

[Ozule]

My ISP is Orange (Spain). The ONET is Nokia G-010G-P

Also I didn't check the double NAT thing... I can see in the Device Manager field that most of my wireless devices have both IPV6 address and local IPV4 address... could this be the reason? Sorry if I'm saying something nosense, this goes far my knowledge. 🙂

Here you have an screenshot of what I can see in Devige Manager field.

It's unlikely but disable IPv6 just in case. If you try to access devices that are connected via the same method e.g. eth2eth, 2.4to2.4, 5to5GHz does it work then?

[Ozule]

I already have IPV6 deactiovated in the Netgear. Also this is what happen to me, 2.4 to 2.4 or 5 to 5 can connect perfectly. Also sometimes I have issues when connecting 2.4 to 5, but it is just the printer. It is just a matter of Wired - Wireless.

[Ozule]

Hi again,

Definitively the issue is that Wireless devices hace double NAT, with an iPV4 and another iPV6. This weird because I have iPV6 deactivated in the router. Any ideas to solve this?

Thanks

[Netduma-Fraser]

If you have IPv6 disabled then reboot the router to clear the IPs. That isn't a double NAT though.

[Ozule]

Hi,

I already did that (several times) and those devices are still getting an ipv4 and an ipv6...

Any ideas?

[Netduma-Fraser]

Disable QoS fully from the Anti-Bufferbloat 3 line option menu and see if that helps the devices communicate.

[plemans]

just to confirm, you're going:

ont------>xr500------->switches/device

are the devices directly connected to the xr500?

or to the switch? 

Do all of them not working wired? 

have you tried disabling sip alg? 

[Ozule]

Hi,

ONT----> XR500------>3 ethernet port directly to 3 devices, 1 ethernet port to Switch with another 4 devices.

All wired devices (Switch or directly to XR500) have only ipV4.

SIP ALG already deactivated...since the very first day.

[Ozule]

I already had QoS Antibufferbloat deactivated. 😞

[Netduma-Fraser]

The devices you're trying to connect to each other are some using the switch? If you do devices direct to the XR to wifi does that work?

[Ozule]

Already tried and same issue. As a note a couple of wireless devices are not getting a iPV6 (Thermostat and Camera) just an iPV4 and with those I have zero issues connecting from wired to wireless.

[Netduma-Fraser]

Are you able to disable IPv6 on the individual devices network settings at all?

[Ozule]

Yes, in fact it was disable by default. I cannot understand why devices have an IPV6 address if this setting is deactivated.

[Netduma-Fraser]

Give them a reserved IP in LAN settings then reboot and that may prevent them getting IPv6.

[Ozule]

Hi,

I tried with my iPad, and although it seems that the router only assigned only an iPV4 after a few seconds it also gives the iPad iPV6.

Any new suggestions? This is super weird...

[Netduma-Fraser]

Could you provide a screenshot of your IPv6 page just to check please?

[Ozule]

Surem here you go

[Netduma-Fraser]

I think this is a beta issue, I seem to be getting the same. Can you confirm whether only wireless devices are getting an IPv6 address?

[Ozule]

Yes, only Wireless devices. About being a Beta issue, I don't think so. I installed the beta 3.0 OS just a couple of days ago. I have been dealing with this issue for a year, but I didn't bothered a lot till now that I'm working from home and I struggle with this issue every day.

Have you got IGMP Proxying enabled?
