By Steve AlexanderQ: I hire a mixture cable modem and Wi-Fi router from the Comcast Xfinity web service for $14 a month. I’d quite purchase a alternative modem than proceed to hire one. How can I discover a suitable alternative?
— James Martin, Maple Grove, Minn.
A: You might have two decisions. Purchase a Comcast-compatible cable modem that has a built-in wi-fi router ($90 to $350), or purchase two units, a suitable stand-alone cable modem ($50 to $230) and a stand-alone router ($30 to $240.)
To search out cable modems with and with out Wi-Fi, learn Comcast’s “accepted modem record” (see tinyurl.com/y2zlt8rv).
Learn the product particulars to search out out if a specific modem consists of Wi-Fi functionality. In case you purchase a modem and a router individually, solely the modem must be Xfinity-compatible.
Q: I take advantage of a three-year-old Chromebook on a safe house Wi-Fi community. Just lately, the Chromebook has been getting disconnected from the web on daily basis about 4:45 p.m. After I unplug and plug within the router, the web works once more. This doesn’t occur with both my laptop computer or pill laptop. What’s flawed?
— Ken Burrows, Colorado Springs, Colo.
A: Given the clocklike precision of your Wi-Fi outage, I believe it’s brought on by outdoors digital interference from one other Wi-Fi community, a gadget or a house equipment that activates at a particular time on daily basis — both inside your home or at a neighbor’s.
Why would interference have an effect on solely your Chromebook? Maybe the interference happens in just one a part of your home. Or possibly you haven’t used your different units at 4:45 p.m.
Listed below are some widespread causes of Wi-Fi interference:
— Neighboring Wi-Fi networks that overlap with yours.
— Microwave ovens, fluorescent lights, storage door openers, cordless telephones and child screens.
— Bluetooth digital units reminiscent of wi-fi audio system, keyboards, mice and key-finders.
— Movement detectors that use radio waves or microwaves, and wi-fi safety cameras.
Whatever the supply of the interference, you may attempt to repair the issue by shifting your wi-fi router inside your home, or not utilizing too many wi-fi units close to one another.
Or, if in case you have a router that makes use of solely the two.4 gigahertz radio frequency, you should purchase a dual-band router that makes use of each the two.4 gigahertz and 5 gigahertz frequencies. The 5 gigahertz frequency travels shorter distances, and is much less more likely to decide up interference from a neighbor’s Wi-Fi.
