Start a New Discussion. Our internet is provided by our cable company. I added an exv2 WiFi extender to the mix and it works perfectly. Great WiFi throughout the home. Turn off the extender and the problem goes away. The cable company has tried a few things but has now said that it is not their extender so I am on my own.
They say there is no reason why an extender should be having this impact. How is an extender killing the cable tv the WiFi always works though and what can I do about it? Go to Solution. Looks like problem fixed. Following advice seen here and elsewhere, I upped the IP lease time on the router from default 1 hour to a couple of days.
No real idea why this works but no crashes for 3 days now. View solution in original post.
Lots of calls to cable company ISP and extender manufacturer accomplished nothing. So I tried something from a Google search and the problem has gone away so far 12 hours and counting. I think this may have been the default. Then went to router and saw it was set to generate IPs of I changed the lower bound to We are continuing to monitor the situation to ensure that the best possible service is provided to our customers.

The router is the beating heart of your home Internet connection. Most importantly, it has fans that keep it from overheating. If your router is in a closet, cupboard, behind the couch, or any other claustrophobic space, consider placing it somewhere more spacious such as a shelf or table.
Avoid cramped spaces like corners, closets, and etc. Quick Fix 2: Change the Channel Change the frequency your Wi-Fi network is using to avoid congestion and interference.
If possible, switch to the 5GHz band.
SB6141: Troubleshooting Internet Connection
Wi-Fi works by transmitting data over airwave frequencies, similar to radio channels. Just like radio in your car, some channels will come through clearer than others. Specifically, channels within the 5GHz band used by newer Wi-Fi routers will generally outperform the older 2. On a Mac, there is a Wireless Diagnostics tool built in for this. As you can see in this screenshot from my own Macbook Pro on macOS Windows users will have to use a third-party tool like NirSoft.
The interface and process is similar — just follow the instructions to install and use on their website. Changing the channel will require you to log in to your router via their web portal. You will type this into your browser just like any other website. Doing so will iron out software bugs that could be causing your home Wi-Fi network to slow down, shut off randomly, or otherwise behave in a less-than-ideal manner. Here are some common options:.
Home Internet connections are similar to the postal service. Data packets are constantly being delivered to your home, or sent out to specific web servers. The only real fix for this is to try to reduce traffic to your router.
Connect stationary devices like desktop PCs via ethernet rather than Wi-Fi if possible. If your router is old, consider purchasing a new one with more advanced features that can handle more traffic. With an increasing number of devices used simultaneously in American households, it may be that your Wi-Fi 5 router can no longer cope. These quick fixes should address the underlying cause of Internet outages in most situations, and help prevent them in the future. Ryan Hunt is a networking expert based in Richmond, VA.
When he isn't nerding out about technology he enjoys making software and traveling. Ping refers to the process of sending data packets to another device and receiving data packets in return. The time it takes for this process to take place is called latency. There are several things you can try to improve ping and reduce latency.
If you use a WiFi connection, move your device closer to the router and disconnect other devices that might be using the same connection.Texas-based information-security firm Nomotion has found five serious security flaws that could let hackers take over your network, inject ads into the websites you view and even directly attack devices on your network.
Arris took over Motorola's home-networking division a few years ago, and many models may bear either company's brand name. These flaws don't seem to affect the Surfboard line of cable modems that Arris markets directly to consumers, but we've asked Nomotion for clarification. You can fix all these flaws yourself, although some require technical know-how and software tools.
Fortunately, the most widespread flaw is the easiest to fix, and we'll show you how. For the rest, please refer to Nomotion's blog posting. Anything that can connect to the internet has at least one unique MAC address. It gives an attacker direct access to all the devices on a home or small-business network.
If you're familiar with the security deficiences of the Internet of Thingsyou'll know that many smart-home devices have little or no protection against attacks coming from within the local network. Combining Vulnerability 5 with known IoT vulnerabilities could lead to attacks on your smart TVthermostat, door locksrefrigerator, etc.
To fix this flaw, Nomotion recommends browsing to IP address Caveat: Nomotion warns that "if you choose to proceed, you are doing so at your own risk and liability. At that web page, you'll see the network device's configuration interface. You'll see form fields in which to enter information. In the Service Name field, enter a name of your choice — "Bypass Block" might be a good one. Enter "" into both Global Port Range fields. For Base Host Port, enter "1". Then click the Add button.
On the next page, make sure your new service is listed under Services, and select it. Then select any one of your existing devices under Needed by Device. That should kill the Port access problem. That firmware update added SSH secure shell access with hardcoded credentials of admin name "remotessh" and password "5SaP9I26". Anyone using those credentials can remotely flash new firmware, change the network name and password, change the network settings or even inject ads.
Fortunately, Nomotion said only about 15, devices worldwide seemed to be vulnerable. If you've got one of those two models, and it's running that firmware check in the admin interface mentioned in the previous flaw's fixthen you've got a little command-line typing to do.
Please refer to Vulnerability 1 in the Self-Mitigation section in Nomotion's blog post. Vulnerabilities 2 and 3 affect the web-server feature on the NVG model.
Why Your Router Keeps Shutting Off Randomly and How To Fix it
It turns out anyone can get administrative access by hitting port with the username "tech" and no password. Aboutdevices seem to be affected, per Nomotion. It gives the attacker the MAC addresses of all devices on the internal network, plus the Wi-Fi password, but the attacker needs to know the serial number of the specific router, modem or gateway being attacked.
As such, the threat of exploitation is low. To fix Vulnerabilities 2 through 4, the user will need to use Burp Suite it's free or a similar web-security tool.This resets the device and frequently improves the speed.
Our aim with this guide is to provide you a to-the-point reference for dealing with some of the most common home WiFi issues, including:. If your wireless connection suddenly stops working, before trying anything else, restart your router.
In most cases, this should fix your issue and allow you to get back online. Most routers have a series of icons that illuminate to convey different status messages at a glance. When everything is working properlyyou can expect the icons to be solid or blinking green or blue light. This signals that a device is plugged in and functioning normally.
When there is a connection issueyou can expect the icons to turn red or orange. An orange or amber light may indicate a problem or limited connectivity, whereas a red or unlit icon may signal that there is no current connection.
Important point : in order to be clear on what your specific device is communicating to you, be sure to refer to the user manual for a more detailed explanation.
Try this: Plug an ethernet cable directly into your router and test your internet speeds using our speed test tool.
Next, test your speeds on the WiFi connection. If they are both slow, the issue is likely with your service provider, and not your equipment. Give them a call. If the hardwired connection is much faster than the wireless one, however, there may be more you can do to optimize your network. First try moving your router to a more central location.
Also, you may be encountering interference from networks adjacent to yours. If you think this may be the case, you can try changing the channel your router is broadcasting on. These tend to be less congested, and therefore better performing than their 2. You could have an unpaid balance that has caused the company to suspend your account, or there may simply be an outage in your area.
Try this: Check to see where your router is positioned. If it is somewhere cramped, such as behind a couch, or crammed into a crowded equipment cabinet, it may be overheating and shutting down automatically to prevent any damage.
For one, your network may have reset itself due to an update. Take a look at the default network name usually printed somewhere on the router itself and see if you recognize that network when looking for a connection. Try this: Turn off the offending device and turn it back on.
You can also try turning the WiFi off and on again in the settings of your device, just to be thorough. If this doesn't help, you may need to delete your network from the device entirely.
Our speed test tool will allow you to see how your current network is performing in terms of both upload and download speeds. You can also use Speed Test periodically to see if you are really getting the speeds that you are paying for. Just remember that using WiFi will always slow things down a little bit! The Network Diagnostics tool is a robust program that allows you to get a clear picture of your network health, as well as troubleshoot any issues you may be experiencing.
When you first open the program, it will scan your immediate area for any available WiFi networks. Choose neither of these.Take wireless networking to whole new.

Are you having a problem with your Internet connection or Wi-Fi? Whatever the problem — from a flaky connection to Wi-Fi troubles or even no access to the Internet at all — some router troubleshooting could fix things.
Some of this also applies to your modem, although many Internet service providers are handing out combined router-modem units these days. Your wireless router and modem may actually be the same device. Have you tried rebooting it? Yes, once again, the lowly reboot is the solution to many network problems. Whether websites are failing to load, everything network-related seems slow, connections are dropping, or your wireless is flaking out, you may just want to try rebooting your router.
Some devices may have a power switch, but the unplug-and-plug-back-in method applies to all routers. Like any other electronic device, routers can fall prey to overheating. This overheating can damage the router over time or just make it unstable. If the vents are blocked or you have the router in a hot location — like on top of a tower PC that heats up — overheating could be causing instability.
This may sound like a no-brainer, but we sometimes forget to check the most obvious solution before moving on to more complicated ones.
Someone may have accidentally pulled on or kicked a cable, causing it to unplug or become loose. Be sure to check the power cables to your router and modem, the cable between your router and modem, the cable between the modem and the wall socket, and each Ethernet cable plugged into the back of the router.
Ensure nothing is blocking the wireless signal, particularly large metal objects or devices that can interfere, like microwaves and some types of cordless phones. Read our in-depth guide to improving your Wi-Fi signal for more information.
Determining the optimal wireless channel for your area and changing your router to operate on that wireless channel instead of a more congested one can reduce this interference, improving your wireless signal. If you have an Android device, the Wi-Fi Analyzer app can help you analyze your area and find the optimal channel.
You can then change the wireless channel on your router. You may want to try resetting your router to its factory default settings if there seems to be a serious problem with its configuration. Your router or modem may be broken. The Ethernet cables you use may be damaged and need replacement. Read our guide to troubleshooting Internet connection problems for more tips. If your router seems unstable no matter what you do or needs frequent resets, consider replacing it.
New routers are fairly cheap and dealing with an unstable router can be a huge headache. The Best Tech Newsletter Anywhere.
