My Tips on the 5 Settings You Should Change on Your Router Right Away
As CNET's router expert, I know a few easy tricks for creating a secure Wi-Fi network and when I bought my own router, these were the first settings I updated -- and you should, too.
Whether you just invested in your own router or you're renting one from an ISP, here is what to update on your new Wi-Fi router to enjoy browsing and streaming safely. For context, I'm an Xfinity (Comcast) subscriber, but the tips here should translate no matter what internet provider you use.
1. Change the network name and password
To change the username and password, you'll need to log into your provider's website or mobile app. Log in to your account and look for a section for Network or W-Fi settings. On Xfinity's website, I clicked WiFi Details to change the name of my Wi-Fi network and set a new password. Choose a password -- or better yet, a passphrase -- that you'll remember but isn't too easy to guess.

2. Choose a security mode
If you set a strong password for your router, then you've taken the first step of securing your network rather than leaving it open for anyone to access. With a password set on a modern router, you are most likely using WPA2 or WPA3 encryption.
Locating local internet providers
WPA, or Wi-Fi Protected Access, is a 256-bit encryption protocol that is more secure than the older, weaker WEP standard that uses 64- or 128-bit encryption. WPA2 improves upon WPA by using a stronger encryption algorithm. It uses the Advanced Encryption Standard (AES) algorithm that is more secure than WPA and its TKIP (Temporal Key Integrity Protocol) algorithm. WPA3 stepped up the security measures even further, strengthening password security, data encryption and smart home connections.
Many routers offer a mixed mode of WPA2 and WPA3 so that older devices that pre-date WPA3 can connect to your network. WPA2 has been around for more than 10 years so it's unlikely that your router is still using WPA encryption. When choosing the security mode for your router, I would go with WPA3 and only switch to mixed mode if you have an ancient device that won't connect to your WPA2-protected network.
3. Check network mode and bands
If you're using a newer Wi-Fi 7 router, it broadcasts in three frequencies: 2.4, 5, and 6 GHz. These are the frequencies with which your wireless network broadcasts radio waves to transmit information. All three frequency bands should be on by default, but check the advanced settings of your provider's website or app to check the status of both to make sure they are active.
The 2.4GHz band is more crowded because it's the frequency many common electronics in your household use, from cordless phones and baby monitors to garage door openers and microwaves. You might run into network interference with 2.4GHz, but it allows older devices to connect to your network. The 5GHz band is less congested and faster but has shorter range than the 2.4GHz band. The 6GHz band is significantly faster than the other two, but it works best when your devic around 15 feet or closer to your router.
With all three modes operating, your router will choose the best mode for each of your network devices.
4. Enable parental controls
Look for a Parental Controls or Access Restrictions section to establish some boundaries for your kids' devices. With Xfinity, click the People tab to set up profiles for your kids. You can assign devices for each profile and then hit Pause for any or all devices of a profile to give them a break from Instagram, Snapchat, texting and everything else on the Internet.
You can also enable parental controls for a profile to "reduce the risk of accessing objectionable websites and apps and enable protective search settings for Google, Bing and YouTube." You'll also find the option to set active hours for your kids' devices. Xfinity calls it Bedtime mode, which lets you set the hours the internet is and isn't available. There are different options for weeknights and weekends.

5. Set up guest network
Creating a guest Wi-Fi network saves you from potentially giving visitors access to shared computers and files on your network as well as the hassle of needing to tell them your complicated or embarrassing Wi-Fi password. In your account settings, look for Guest Network or Home Hotspot.
Matt Elliott/CNET
With Xfinity, I couldn't find this setting with the other Wi-Fi settings but instead had to move a level up to my general account settings. From the main account page, it was listed under Settings. With it enabled, Xfinity started broadcasting a separate network called "xfinitywifi" that guests can use without needing to track me down for a password.

Tesla Stumbles, but Elon Musk Gets a Massive Payday
Key Points Tesla's sales are struggling in key markets overseas. Consumer backlash from Elon Musk's political stance is real. These 10 stocks could mint the next wave of millionaires › Unless you've been purposely hiding from the news -- which would be understandable -- you know that investors in Tesla (NASDAQ: TSLA) have had plenty to digest. Between allegations Tesla isn't paying its bills and hurting small businesses, to facing consumer backlash from CEO Elon Musk's political tour (and we can't forget the sliding sales and global profits), it's been a full downpour. Let's consider the recent speed bumps, as well as Musk being rewarded with a hefty $29 billion payday. The overseas spiral July figures are seeping in from Europe, and they show that Tesla registrations checked in 41.6% lower compared to the prior year, despite sales of electric vehicles (EVs) surging across the Continent. It's a continuation of the sales spiral the EV maker faced during the first half of 2025. And the problem is that the decline was supposedly due to the new Model Y being in limited supply -- but the issues appear to be deeper than that. The story is similar in China, another crucial market for Tesla. Its sales of China-made EVs dropped 8.4% in July compared to the prior year. That was a reversal from the small gain Tesla posted in June, which at the time reversed an eight-month losing streak. The consumer backlash The consumer displeasure is real, and Musk's political allegiances have pushed some buyers to new and different brands. There's evidence of the effect this is having on Tesla's once-spotless brand image, according to new data from S&P Global Mobility, which tracks sales data across the automotive industry. The new data, shared with Reuters, showed that Tesla's consumer loyalty took a nosedive in July 2024, correlating with Musk's public commitment to an anti-environmental political campaign. According to Reuters, Tesla's loyalty peaked at 73% in June 2024 before bottoming out in March at 49.9%. No matter how you slice it, that's a quick and dramatic decline in consumer sentiment, literally driving buyers to another brand. A massive payday Tesla's board granted Musk 96 million shares, worth roughly $29 billion, in an attempt to keep the billionaire focused on the EV company amid his multiple businesses and ventures. The vote comes after a 2024 Delaware court ruling that voided Musk's 2018 compensation package, which was valued at over $50 billion. The court said the approval process was flawed and unfair to shareholders. According to Automotive News, the special committee that was formed to consider the new pay package said: "While we recognize Elon's business ventures, interests and other potential demands on his time and attention are extensive and wide-ranging ... we are confident that this award will incentivize Elon to remain at Tesla." What it all means Tesla and its investors certainly appear to be at a crossroads. While selling EVs and zero-emission credits keeps the lights on for the young company, it constantly reminds investors that its future may be more in line with artificial intelligence (AI), robotics, and robotaxi services. Long-term investors should stay the course but should also prepare for a bumpy few quarters as the company works through its upcoming identity crisis, the slow ramp-up of the robotaxi, and an aging lineup. Should you buy stock in Tesla right now? The Motley Fool Stock Advisor analyst team just identified what they believe are the for investors to buy now. The 10 stocks that made the cut could produce monster returns in the coming years.

Flying Cars Aren't Just Science Fiction Anymore. This Company Is Leading the Charge in eVTOLs -- and Yes, It's Publicly Traded.
Key Points Joby's electric air taxis promise emissions-free trips over congested cities at speeds up to 200 mph. Partners like Toyota, Delta, and Blade give Joby cash, infrastructure, and market access ahead of launch. With no revenue yet and trading around 20 times book value, the market is betting on impeccable execution. 10 stocks we like better than Joby Aviation › The idea of hailing a flying car has always belonged to science fiction. But thanks to Joby Aviation (NYSE: JOBY), the idea of catching a flying taxi is slowly edging into reality. The company's electric vertical takeoff and landing (eVTOL) aircraft are designed to carry passengers over congested cities at speeds upwards of 200 mph. And they are quieter than a helicopter and have zero emissions. This vision isn't theoretical. Joby has already demonstrated eVTOLs in New York and Dubai and is moving through the Federal Aviation Administration's (FAA's) certification process as I write. With major strategic partners, a strong cash position, and an aggressive market expansion plan, Joby could be one of the first to make commercial flying taxis a real business. The question for investors is whether this growth stock is ready for takeoff today, or might it be wiser to wait until the company has a little more grounding? From blueprints to boarding passes Joby is trying to solve a problem that most city drivers face everyday: traffic. And not just any traffic. Horribly congested traffic, the kind that makes you wish you were anywhere (even at the DMV, with slow internet) but stuck in it. To get there, however, Joby needs a few things to work in its favor. The first is full FAA-type certification, the regulatory green light that will let it fly passengers in its eVTOLS. The second is the infrastructure to make its vision practical, that is, a network of vertiports, charging stations, and terminals in the right locations so customers can board, fly, and land without the experience feeling like more hassle than just staying in the car. So far, the company has checked off some big early boxes. It already holds FAA Part 135 certification, which means it's cleared to operate as an air carrier with approved aircraft. It's also moving to lock down prime real estate for takeoff and landing, from Manhattan heliports to Dubai's planned aerial taxi hubs. But that doesn't mean the company is smooth flying -- yet. Its biggest "unknown" is time. Every month that slips by without full FAA certification pushes profitability that much further into the future. Add in the fact that it's burning cash each quarter, and you start to see why patience -- and a deep cash cushion -- are non-negotiable. Big names, big bets Speaking of cash, where is Joby getting money for research and development? Well, here's where the story gets interesting. Although Joby is pre-revenue, it has an impressive ecosystem of backers and partners. Back in 2022, Delta Air Lines (NYSE: DAL) invested about $60 million in Joby, with the expectation that Joby would eventually create a premium service for Delta customers. More recently, Toyota (NYSE: TM) committed $894 million to helping Joby with certification and commercial production of its electric air taxis. In perhaps its boldest move, Joby plans to acquire Blade Air Mobility (NASDAQ: BLDE), which would help it gain access to central terminals in New York, Southern California, and Europe. Meanwhile, international expansion is already underway. In Dubai, Joby signed an exclusive six-year agreement with the Roads and Transport Authority (RTA) to launch aerial tax services there in 2026. Finally, Joby recently announced that it's partnering with L3Harris to develop hybrid eVTOLs for defense applications, with demonstrations planned in 2026. Things seem to be rolling. But before we get too bullish, let's look at its finances. The numbers under the hood Here's where reality checks in. Over the last 12 months, Joby generated just $110,000 in revenue, essentially none, while recording a net loss of about $596 million. Just in the first quarter of 2025, it posted a loss of $82 million, or $0.11 per share, driven largely by spending in research and development. To add fuel to the fire, cash burn was $111 million for the quarter. The balance sheet, however, is a strength, largely because of partners. Joby holds about $813 million in cash and short-term investments. That net cash position gives the company some runway to fund operations without immediate dilution. Still, with a market cap near $17 billion, the stock is priced well ahead of fundamentals. It's price-per-book (P/B) ratio -- which measures how richly the market values the company relative to the net assets on its balance sheet -- sits around 20. That's steep compared with the S&P 500's median of about 3. Even Archer Aviation (NYSE: ACHR), Joby's primary competitor, is trading at roughly 5.6 times book value. That doesn't mean Joby can't grow into its valuation, but it does underscore how much future success is baked into today's price. Verdict: Should you hitch a ride? When people talk about Joby's risks, they usually circle the big ones: FAA certification, steady cash burn, competition. But there's a second layer of risks -- call them structural -- that could make investing in Joby choppy in the short term. Start with the skies themselves. Urban airspace is already a juggling act, and air traffic control in cities like New York and LA runs hot most days. If regulators decide to keep eVTOL traffic on a tight leash, Joby's flight schedule could end up thinner than its business plan assumes. On the ground, vertiports have to be built, and convincing neighborhoods to welcome them is another story entirely. Costs could also be a problem: insurance, pilot pay, and battery charging might keep fares higher than commuters are willing to swallow. Still, if you believe Joby can navigate these headwinds and execute on time, the payoff could be big. For long-term investors who can tolerate volatility, this is a speculatve bet on a market that doesn't exist yet but could make ground transportation look radically different ten years from now.

How Quantum Computing Could Upend Bitcoin
Investors in Bitcoin should pay attention. Experts say that ultrapowerful quantum computers could eventually crack the security codes of blockchain, the underlying technology for Bitcoin. Roughly a quarter of all Bitcoins are now protected with algorithms that could be cracked by quantum computers in five or 10 years, Gartner analyst Avivah Litan tells Barron's. Those are mostly older Bitcoins housed in digital vaults, or wallets, that date back as far as 15 years. Solve the daily Crossword
