Needed: a wireless router with PSP

Can someone recommend a simple wireless router with Power Save Polling (PSP)? I need to install one behind the U-verse RG for the sake of our battery devices.

 

I'm tired of our battery operated devices (iPhones, Ipad, etc.) depleting their batteries when connected to to my 2Wire RG, even when not in use. At home, we have to either plug in our devices or turn off Wi-Fi when not in use, or the constant polling by the RG will still drain the batteries. This was normally not an issue because we often plug in to recharge at the end of the day. (If not, the device will be nearly dead in the morning.)

 

The issue came to head after installing a Nest thermostat, however. The battery on this (wireless) thermostat gets a trickle charge from the HVAC system control currents, but it isn't enougfh to keep up with the constant polling from the RG. I was forced to turn off Wi-Fi for the thermostat to work properly, but the neat advantages of the Nest are lost when doing so.

 

Hence, the need for a router with PSP or PSM. I understand that some routers have this feature, but not properly implemented. Can anyone recommend one?

Actually, I have since learned (after speaking with a LAN expert), that PSP is not implemented in the Nest, but Automated Power Save Delivery (APSD). This is a newer power save management method implemented in most new 802.11 devices under the WMM standard, replacing PSP. Most newer, better quality routers and wireless APs are APSD compliant, as well as smartphones and other battery-operated WiFi devices (not just the iPhone). I regret using "PSP" in the thread title, as it seems to have caused some confusion.

 

Anyway, I do have a C wire, but it is not energized (I only have a single-zone system). I had already asked the Nest TS if I should get the C wire energized and he said it wasn't necessary, that a more elegant soution (for the benefit of my opther battery-operated devices) would be to upgrade to a power save compliant router. That's when I started this thread.

 

So I'm giving kudos to gregzoll and Computer Joe for taking the time to help out. I still haven't decided which route to take, but most likely at this point I'll see about energizing and hooking up the C wire. I don't feel like buying more equipment and tinkering with my network just for the benefit of the thermostat and mobile devices.



If the "C" wire is already in the thermostat cable at the thermostat your half way there. if you can let us know whether your system is self powered (all wires go to furnace control panel) or externally powered (uses a control transfomer) we can let you know how to wire it if your not sure how to do it.

Thanks. My furnace is in the attic, so I'll take a look at the control panel this evening.

Re: Needed: a wireless router with PSP

With the pleasant weather today, I shut off my AC at the panel and ventured into attic to examine the furnace control board. Sure enough, the common (blue) wire was not connected. But another one was, coming from a 2-wire pair. The connections were as follows:

 

                                mystery wire 

                           R                         B

                            |                          |

                            |                          |

                           v                         v

                R         Y          W        COM      G

                ^           ^          ^                        ^

                |            |            |            x          |

                |            |            |             |          |

               R           Y         W           B        G   

                                thermostat wire

 

I connected the blue thermostat wire to the COM terminal, and everything works fine. The Nest battery is also charging.

What I'm curious about is the other wire connected to the board. I coudln't trace it after it enters the wall. Again, I only have a single zone system/ Any clues from those familiar with HVAC?

Do you have a heat-pump?

No heat pump; gas furrnace, electric A/C.

Then those "mystery wires" probably go out to energize the coil on the contactor that starts your compressor/condensor unit.
