Un tel bordel dans la non maitrise de la connectique laisse pantois. Je vais finir par croire qu'ils ne testent pas. Pas d'option Bluetooth dans l'Apps On s'en fout du Wifi!! On veut du Bluetooth! Le son bordel!!! Pourriez-vous m'indiquer le statut de l'option "RSSI puissance du signal"? Malheureusement pas possible de tester la connectique ethernet car absente physiquement parlant de la ST Activer les suggestions.
Hopefully someone somewhere and get this issue fixed before many people are left with no way to connect to routers and get access when they need it. Because not everyone knows how to fix these issues like i do.
This thread is locked. You can follow the question or vote as helpful, but you cannot reply to this thread. I have the same question Report abuse. Your computer should be checked first. To eliminate this possibility, shut off your computer. Wait a few seconds and then restart. Check that the "online" or "cable" light is lit and stable on your modem. Otherwise, the modem may not be connected to the Videotron network.
Reset the modem as indicated below. How to reset the modem:. Security software firewall, antivirus can cause connection loss if it's not configured properly.
You will have to verify the configuration of the firewall or antivirus software. Please note: You have to reset the modem every time you plug in a new peripheral, whether it's a router or another computer. If your connection problem continues, please contact one of our technical support agents at or Videotron is recognized for the reliability of its network and Internet access.
Nevertheless, a number of external factors can affect the speed of your connection. Your installation: The router, often used to connect a number of computers to the Internet, can cause a slowdown.
Many factors can cause this:. Your computer: The state of your computer can also influence your Internet access. The presence of a virus or Trojan horse, an incorrect configuration of your firewall, and certain procedures updates, saves, antivirus analysis, etc.
Your usage: The sites: Access to high-traffic sites can be saturated. Your connection may become slow as a result. Lastly, there are many unknowns on the Internet. Like all networks, the Internet can get congested. Videotron is constantly improving its network to spare its clients such inconveniences. An in-house study showed that the effective range of a VoWi-Fi phone drops by 50 percent with an interference device cordless phone or video camera at a distance of 75 feet from the access point.
This 50 percent reduction in the range of your phones would likely result in coverage holes over 75 percent of your floor space. Summary: Can you hear me now? Voice over Wi-Fi and interference don't mix. Myth "Interference is a performance problem, but not a security risk.
If an Internet worm got through your corporate firewall and was using up 50 percent of your corporate network bandwidth as it spread from machine to machine, would you consider that a security or a performance concern?
The point here is that anything that impacts mission-critical corporate IT systems is a security concern. As your corporate Wi-Fi network becomes more and more mission-critical, any possible interference device-whether the interference is malicious, as in the case of a jammer, or accidental-must be viewed as a potential security issue. Wi-Fi networks are typically locked down with secure access controls, but devices that run on non-Wi-Fi networks, such as Bluetooth devices, are not.
Preventing accidental bridging between insecure networks and the corporate networks requires: 1 client-based tools that control configuration of wireless network interfaces, and 2 RF monitoring that watches for suspicious non-Wi-Fi activity indicating possible bridging.
Most enterprises implement some form of Wi-Fi rogue access point detection to find unauthorized and frequently unsecured access points on the corporate network. But there are non-Wi-Fi devices such as Bluetooth access points that can open up a similar security hole.
Like Wi-Fi rogues, these devices must be detected and eliminated. Certain non-Wi-Fi devices such as cameras and cordless phones can be used to carry sensitive data out of a restricted area, bypassing corporate security policies. When this is a concern, a zone of restricted wireless operation should be established, and that zone should be enforced through monitoring of the spectrum for unauthorized devices.
Summary: RF security doesn't stop with Wi-Fi. Do you know who is using your spectrum? Myth " Systems that use multiple antennas or smart antennas are able to increase immunity to interference by boosting the desired signal seen at a receiver.
When the desired signal is stronger, the ratio of that signal to interference referred to as signal-to-noise ratio or SNR is also improved. Effectively, this reduces the zone of interference associated with a particular interference device to a smaller area. But the gain achieved by a smart antenna system is typically only on the order of 10 dB of enhanced signal power. This means that the range of interference might be shrunk by a factor of 2 over a traditional antenna system, but even then the interference problem is far from solved.
For example, if a device would have previously caused problems at a distance of 80 feet from the receiver, it will still cause problems up to 40 feet from the receiver. Thus you would have square feet of floor space where the interference is still a problem! Summary: Antennas are a pain reliever, but far from a cure. Myth "My site survey tool can be used to find interference problems.
A standard Wi-Fi site survey tool is designed to measure Wi-Fi coverage. It uses a Wi-Fi chipset to measure the signal strength of access points as you move around the building. Unfortunately, Wi-Fi chips are designed to see Wi-Fi signals only, and can't tell you much about interference from other non-Wi-Fi devices. This is the same limitation experienced when using a Wi-Fi packet analysis tool.
A Wi-Fi site survey tool might indicate a general area where a non-Wi-Fi signal was observed. But the tool can't help you determine the nature of the interference, the type of device causing it, or where the device is located. So you are left without a solution. You really need an RF-level tool to diagnose interference problems. The good news is that a few of the next-generation Wi-Fi site survey tools are being more closely integrated with RF-level tools in order to implement a complete solution.
Summary: Site survey tools measure coverage, but don't solve your RF needs. Myth "RF analysis tools are too bulky and too expensive.
Many RF analysis tools such as large and expensive spectrum analyzers are not enterprise friendly. But Cisco's RF spectrum analysis tools are designed to fit both your desired form factor small cards that plug into your laptop and your IT budget. And to make things even better, Cisco's spectrum intelligence solutions makes being a RF expert unnecessary. Buy or Renew. Find A Community. Cisco Community. Thank you for your support!

Detailed Troubleshooting Steps Diagnosing a Router Problem If however the wifi light is off for a few seconds, before coming back on this indicates that the router has reset itself, generally when this happens if could be an overheating issue, try making sure it has plenty of ventilation on all sides.
The hard reset By performing this you will lose all of the routers settings, as everything will be set back to its original default settings, you will need to setup the router again from scratch so make sure you have the connection details to hand.
Diagnosing a Computer Problem if a computers wireless connection keeps dropping follow the list below, this will hopefully enable you to resolve the problem.
Interesting good to know information RF interference can be a major inhibitor to wireless performance, creating security vulnerabilities and wireless network instability. Ken Hagen.
