Buying a New Bath Fan When you’re picking out a new fan pay attention to CFMs and sones. Sones indicate how loud a bath fan is—the higher the number the louder the fan. 2 sones is considered quiet. CFM stands for cubic feet per minute. It’s the measurement of airflow. The larger the room, the higher the CFM number you’ll need. It’s best to get a fan that’s rated for the size of your bathroom. Here are a few CFM recommendations: Powder room: 50 to 60 CFM Medium-size bathroom: 70 to 90 CFM Large master bath: 100+ CFM Also note the size of your old fan. The easiest replacement is to get a new fan that’s the same size as the old one. You can take your old fan to the store to check. Remove the Old Bath Fan Cover the work area with a drop cloth. Turn off the power to the fan. Take off the cover and use a circuit tester to doublecheck that the power is off. Take out the mounting screws. Some may have to be removed from the attic.

Slide the housing to the side and disconnect the vent duct. Pull down the housing and label the wires. Then disconnect the wires. Install a Larger Fan Hold the new fan housing up to the ceiling and mark it. Cut the hole with a drywall knife. Install a Smaller Fan To make the hole in the ceiling smaller you’ll need to patch it with a piece of drywall. Determine the size of the hole you’ll need and cut a piece of drywall to fit. Also cut a 1-by-2 just a little longer than the hole opening. Attach the drywall piece to the 1-by-2 with screws. Slide it into place and secure it in the hole with drywall screws. Apply joint compound over the seams and let it dry. Sand it smooth, then apply a little more joint compound. Sand one more time and finish up with primer and paint. Some fans require setting the duct connector in the ceiling first. Hold the housing up, lining up the connector with the slots, and slide the housing into the hole. If you don’t have an attic or access to your attic, check your manufacturer’s instructions for recommendations.

Typically, you would need to frame part of the hole. Cut a 2-by-4 to fit between the ceiling joists and secure with screws. Remember to keep the vent side clear. Keeping the housing level and square with the joists, drive screws through the mounting holes into the joists. The next few steps should be completed in the attic. Skip this step if you added extra 2-by-4 bracing between the joists. From the attic, set a board to kneel on near the fan. Attach the brackets to the joists. Then connect the brackets to the fan body with screws. Attach the ducts to the connector with HVAC tape. Hook up the wiring by first removing the junction box cover. Then connect the house wires to the fan wires: ground to ground, neutral white to neutral white, and hot black to hot black. Replace the junction box cover and turn on the power. If the fan sounds loud like something isn’t right, turn off the power and check that it’s mounted securely and level. If it sounds ok, add the mounting springs and push the cover into place.

There are 50,000 paying Xfinity customers in Houston, Texas who are now broadcasting free WiFi that anyone can use. As far as Comcast is concerned, of course, this is a genius move to blanket the country in high-speed WiFi (and there are plans to hijack millions more modems by the end of 2014) — for Comcast’s customers, though, this is egregious monopolistic overreach taken to the next level… and it’s possibly illegal as well.

First, let’s run through the technical details of Comcast’s Xfinity WiFi Home Hotspot setup. Over the last couple of years, Comcast has been distributing the Arris Touchstone Telephony Wireless Gateway Modem to new customers. Comcast remotely programmed these modems to broadcast a new wireless network SSID — “xfinitywifi” — that gives two one-hour sessions per month to anyone, or unlimited access to other Comcast customers. Comcast says the new wireless network is completely separate from your existing home network, and that public WiFi users don’t have access to any shared files or resources. Exact details of the setup aren’t yet known, but it sounds like some kind of VLAN. Now, let’s tackle the rather thorny questions raised by this scheme. Speaking to the Houston Chronicle, Comcast says this new service won’t slow down the residential customer’s connection. / and click the Users & Preferences section). Comcast says that it alerted the first 50,000 users by post last month, and that less than 1% of customers opted out.

It’s also worth noting that you’re exempt from Comcast’s new scheme if you use your own modem, too.The FAQ does note, however, that “there can be some impact as more devices share WiFi” because both networks share the same slice of 2.4GHz or 5GHz spectrum. From what we know about WiFi congestion and the importance of using the right channel, just having one person using your Xfinity WiFi could significantly slow down your own WiFi network.There could be some privacy and security concerns, too. Comcast has released an Xfinity WiFi app for finding nearby hotspots — and yes, if your residential modem has been co-opted by Comcast, it will show on the map. (Your exact address won’t be shown, but the red blob will be centered on your property.)The more curious bit is Comcast’s assertion that this public hotspot won’t slow down your residential connection — i.e. if you’re paying for 150Mbps of download bandwidth through the Extreme 150 package, you will still get 150Mbps, even if you have five people creepily parked up outside leeching free WiFi.

This leads to an interesting question: If Xfinity hotspot users aren’t using your 150Mbps of bandwidth, whose bandwidth are they using?There are two options here. Comcast might just be lying about public users not impacting your own download speeds. The other option is that Xfinity WiFi Home Hotspot uses its own separate channel to the internet. This is entirely possible — DOCSIS 3.0 can accommodate around 1Gbps, so there’s plenty of free space. But how big is this separate channel? And if there’s lots of spare capacity, why is Comcast giving it to free WiFi users rather than the person who’s paying a lot of money for the connection? And isn’t Comcast usually complaining about its network being congested? At least, that’s the excuse it used to squeeze money from Netflix, and to lobby for paid internet fast lanes.With 50,000 hotspots enabled in Houston today, 150,000 more planned for the end of the month, and then 8 million more across Xfinity hotspots across the US before the end of 2014, we can only assume that Comcast has a lot of extra capacity.

Either that, or it’s intentionally trying to clog up the network for its paying customers — perhaps so it can levy further charges from edge providers like Netflix, or so it has some ammo in the continuing battle for net neutrality. [Read: AT&T moves to acquire DirecTV to defend against Comcast – everyone loses.]The big picture, of course, is that Comcast wants to compete with AT&T, which already has a large nationwide network of WiFi hotspots. It’s also worth noting that, following a spectrum sale to Verizon last year, Comcast now has access to Verizon’s mobile network. Comcast could be building towards a future mobile telephony system that bounces between free WiFi hotspots and Verizon’s network, depending on what’s currently available. Finally, a thought experiment about the legality of Xfinity WiFi Home Hotspot. Comcast owns the Arris Touchstone modem that you rent as part of your monthly subscription, and thus is fairly free to do whatever it likes with regards to setting up a secondary network.
