Wireless Receiver Brings Down Network When Plugged Into Ethernet

I have a 2-wire 802.11b/g gateway connected to a wired u-verse DVR and a u-verse WAP for the wireless receivers.  I then have 2 wireless receivers.  One of the receivers I use wirelessly, but the other is connected via ethernet because its primary location is very far from the WAP.  Both receivers are paired with the WAP, but only one is actually running wirelessly.

 

This setup worked fine until this weekend, when the wireless receiver that was connected via ethernet started acting up.  I rebooted that receiver, and it booted back up into update mode (gear with progress bar, then 2 gears with progress bar, then a few more reboots. then back up).  Now, when I plug ethernet into that wireless receiver, it causing packet loss across my entire WAN.  When I plug that receiver into the LAN, my other two receivers will start to show really gittery picture/audio, and a ping to Google's DNS (8.8.8.8) will start to have 50-60% packet loss.  The second I unplug the ethernet from the wireless receiver, the problem stops. 

 

I called tech support and the said they found a problem outside and were going to send an outside tech, but my service works fine as long as this one receiver isn't connected to ethernet.  I've only seen packet loss like this before when two devices on the same LAN have the same MAC address. 

 

Is it possible this could be because the wireless receiver is paired with the WAP and connected to the LAN at the same time?  Doesn't seem likely, but the only other thing I can come up with is that the NIC on the receiver is shot.  Either way, it feels like AT&T may be wasting my time investigating outside, unless there is actually another problem in addition to this one.

You could try swapping the two wireless receivers and see if you get the same behavior.  You could also try swapping the ethernet port on the RG that your using for the box that's giving you issues..  Maybe it's acting flakey.

Thanks.  I'll try those solutions tonight.

What else is connected to the same port of the RG as the STB that is causing the issue?

Re: Wireless Receiver Brings Down Network When Plugged Into Ethernet

I've tested it in a few different scenarios.  The RG is in an office on the second floor of my house.  There is an ethernet drop that goes from that floor down to the master bedroom, and another drop from that floor to the living room.  The RG has a 1-foot patch cable to each drop outlet in the office, and a 1-foot patch cable from the drop outlet in the bedroom to the wireless receiver.

 

In the living room, the outlet is connected to a Cisco wireless router that is configured in bridge mode so it is just a wireless access point and switch. 

 

So, I have tried the wireless box connected directly port 1 on the RG via the bedroom ethernet run, and have tried it connected to port 2 on the RG by connecting it to the cisco router-turned-AP in the living room.  In both configurations, it causes packetloss across the entire LAN.

Ah ha!!  Any of the STB's or DVR's must be on their own Cat 5e run to the RG.  They cannot be plugged into any other router or once turned on they will flood the dataswitch or router with the IP TV traffic and make the internet inoperable.

OK, well, I had 2 out of 3 boxes connected to a switch for the last month with no issues until yesterday.  Also, if they need a dedicated run, why does the network go haywire when I give the wireless receiver a dedicated run?

Also, the U-Verse guys GAVE me a 4-port switch when they installed.  They never mentioned not to plug a receiver into it.  I appreciate your assistance, but that doesn't seem like the problem I'm experiencing.

What kind of switch is it? 

A switch does not have to be Gigabit, it can be Fast Ethernet (100Mbps), but it must:

 

• Support 802.1p priority queuing

• Must have enough processing power to not be overwhelmed by excessive multicast/broadcast traffic.  Many 100 Mbps switches do not meet this requirement, that is why Gigabit is often recommended even though the bandwidth isn't required.

 

I have one of these and it works fine.

Re: Wireless Receiver Brings Down Network When Plugged Into Ethernet

Is the wireless receiver paired with the cisco WAP at the same time?

Re: Wireless Receiver Brings Down Network When Plugged Into Ethernet

I have tried several different switches, all with the same result.  I tried a netgear 5-port gigabit switch, a 3Com 2900 serials 24-port gigabit switch, and an Apple time capsule set in bridge mode with all devices and RG connected to the LAN ports.

 

In my living room, where everything is working fine (as long as the wireless receiver is not plugged into ethernet), I have the drop from the RG plugged into a LAN port on a cisco 802.11 AC smart wifi router, with the router configured to bridge mode so it servers as a switch and wireless AP.  My u-verse DVR and a few game consoles also connect to the smart wifi router LAN ports.  This setup has been working for well over a month without issue.

I assume the wireless receiver is paired with the WAP at the same time it is plugged into ethernet.  When I reboot the receiver it never asks me to pair, and it works when I disconnect the ethernet.  I don't know if the WAP connection stays active when the ethernet connection is established.

Re: Wireless Receiver Brings Down Network When Plugged Into Ethernet

I would say it's possible the box being paired to WAP and connecting over Ethernet simultaniously may be an issue. You could try disconnecting power to the cisco WAP, then reconnect the box to ethernet and see if your network stays up. If it does, you can perform a disaster recovery on the wireless box while connected to ethernet to remove the pairing.

Do you have details on how to do the disaster recovery?  That is information I've been looking for.

Disaster recovery can only be done on a DVR as far as I know.  Here is a link to how to do it: http://www.youtube.com/watch?v=aQq0OjqVUGU
