Error message “Error opening page: Hotspot login cannot open the page …” when connecting iPads to the CMV Wi-FI
We are aware of a false error that gets reported when certain iPads connect to the CMV Wi-Fi.  Once you tap the OK button, the system will continue to connect.  Sometimes this process will get stuck and if so, simply try again and reconnect to the CMV Wi-Fi.  You should not see this error on the second connection attempt.

This issue has been reported to the manufacturer and we are working closely with them to help resolve this issue.  It only seems to affect certain iPads and does not have a negative impact on your usage of the system.  It can safely be ignored.

Where can I access the City of Mountain View Free Wireless Internet? (CMVWiFi)
The name of the network is "cmvwifi" and is available in the following buildings: 
  • City Hall, 500 Castro Street, Mountain View, CA
  • City Library, 585 Franklin Street, Mountain View, CA
What do I need to connect to the City of Mountain View’s Free Wireless network?
A wireless (Wi-Fi) enabled computer or other device such as a smartphone, netbook or tablet. Most laptop, netbook and tablet computers today have built-in Wi-Fi capability, as do many smartphones. If your computer is not Wi-Fi ready, you can purchase a Wi-Fi network card or network adapter to add wireless capability. This system is 802.11b/g/n compatible.

You will also need a web browser such as Internet Explorer, Safari, Chrome, Firefox, etc. Mountain View Free Wi-Fi works with most browsers in use today.

How do I connect to the CMV Wi-Fi network?
If you're familiar with using Wi-Fi networks, follow these instructions:

  • Open your device's connection manager
  • Connect to the network name "cmvwifi"
  • When you're connected to the CMV Wi-Fi network, you will have to accept the City's Terms of Usage by clicking on o tapping the "Accept Button"

You can then open your Internet browser and use as normal

If your device becomes inactive for a period of time, you will probably be disconnected from CMV Wi-Fi. However, your system should automatically establish your connection when the device is active again.

If you don’t have a Wi-Fi enabled computer?
If your computer doesn't have Wi-Fi built-in, you can add it with an external USB Wi-Fi network adapter or modem. You can buy an adapter from most electronics retailers or online. For best performance, look for an 802.11 b/g/n compatible version. Please refer to your computer or device user manual for more information.
Using a Wi-Fi modem to connect to CMV Wi-Fi
If your computer or device has Wi-Fi capability you don't need an external Wi-Fi modem. However, if your computer or device does not have built-in Wi-Fi capabilities you can use a Wi-Fi modem to connect a desk computer to the network. If you are having difficulty connecting to the network once your computer or device is Wi-Fi enabled, it is likely you are not connecting effectively to the CMV Wi-Fi access point. The CMV Wi-Fi network is not intended to provide connectivity outside of the buildings and the public access areas within a short range outside of these buildings and any incidental availability of the network is not supported.  Please refer to your computer or device user manual for more information.
Sending and receiving email with CMV Wi-Fi
You can read and send email using standard Web-based e-mail services
such as Gmail and Yahoo! Mail. You can also use an email program or an email client such as Outlook and Apple Mail. (See also "Can't send e-mail from CMV Wi-Fi" in these FAQs.

Staying connected to the CMV Wi-Fi network
Most devices automatically save your network connection information. If your device or computer does not automatically save network connection information, see your user manual for instructions
Using secure websites with CMV Wi-Fi
Although you can access secure websites with CMV Wi-Fi, these sites do not protect the information sent from your device to the CMV Wi-Fi access point. It is strongly recommended that you do not conduct personal business across this or any other open Wi-Fi network.
Accessing the CMV Wi-Fi network in other areas
The CMV Wi-Fi system is not designed nor intended to deliver Internet connectivity away from the public buildings and areas listed in the earlier FAQ "Where can I access the City of Mountain View Free Wireless Internet? (CMVWiFi)" and the public access areas directly outside of these buildings.  Any other use is not supported by the CMV Wi-Fi system nor the City of Mountain View Free Wi-Fi program. The City of Mountain View staff cannot respond to requests or trouble tickets associated with indoor connectivity.
Possible interference with personal or private wireless networks from CMV Wi-Fi?
As the CMV Wi-Fi network has been designed to use the minimal radio footprint it should not interfere with your personal or private wireless network. However, if you suspect interference between your network and CMV Wi-Fi, you may want to change the channel of your local router. Check with your router manual for instructions.
CMV Wi-Fi network speed
Mountain View Free Wi-Fi provides up to 3 Mbps download and 2 Mbps upload connections. This is comparable to most high speed personal network connections. However, like most wireless networks, too many users at once can slow the system down.  The City of Mountain View reserves the right to adjust this either faster or slower based on usage statistics to ensure a consistent and reliable connection for all users.
High Bandwidth usage on CMV Wi-Fi
High-bandwidth services such as streaming audio and video, and interactive gaming are not handled well across this system. Please use your home or business DSL or cable Internet for activities that demand a lot of bandwidth.  This is a shared community resource and should remain available for everyone's use.
CMV Wi-Fi connection instructions for Windows, Mac OS or other operating systems
Refer to your user manual for Wi-Fi connection instructions.
CMV Wi-Fi connection instructions for tablets, smartphones, and other mobile devices
Refer to your user manual for Wi-Fi connection instructions.
Poor wireless performance
CMV Wi-Fi is optimized for usage within the buildings designated and the public access areas directly around the outside of these buildings.  It is broadcasting at an appropriate power to achieve this coverage with a guaranteed coverage area of 95% or higher but may also be available at much longer distances.  Every Wi-Fi system has limitations. Your connection may be limited by:

  • Your distance from the nearest access point
  • Obstacles such as trees or buildings
  • Interference from other local networks
While the City of Mountain View is not actively preventing your ability to connect outside of these designated areas, connectivity is not guaranteed and cannot be supported by City Staff
Device is associating to another network, not CMV Wi-Fi

This can happen when there is more than one wireless network within range. Your device may be associating with another network because:

  • The other network has a stronger signal
  • Your device identifies the other network as a preferred wireless network




Can’t send e-mail from CMV Wi-Fi
To curb e-mail spamming, CMV Wi-Fi blocks outgoing connections on port 25 - the default e-mail or SMTP setting. If your e-mail client is configured to use port 25, you can receive, but not send, e-mail. To send e-mail via CMV Wi-Fi, your e-mail program must use a method called Authenticated SMTP, which uses port 587. For more information, check with your e-mail provider.
Switching between different networks
Refer to your user manual.
CMV Wi-Fi network privacy and security
To make the CMV Wi-Fi service easily accessible to as many Wi-Fi enabled devices as possible, CMV Wi-Fi is an open-access wireless network, and the signal is not encrypted. It is strongly recommended that you do not conduct personal business across this or any other open network.
Protecting against spam, pop-ups, and viruses on CMV Wi-Fi
When using CMV Wi-Fi, you should protect your computer or device with commonly available security strategies such as firewalls, anti-virus/anti-malware software and other applications designed for your computer or device. The City of Mountain View does not offer these services as a part of its free Internet program.  Refer to your computer or device user manual.
