The weak security label under a WiFi network's name looks alarming, and it started appearing for plenty of Virgin Media customers the moment Apple tightened its standards in iOS 14. The good news is that it points at a hub setting rather than a hacker. Clearing it takes a few minutes in the hub settings, and the same visit is a chance to tighten up the things that genuinely matter.
The weak security message on an iPhone or other device means the Virgin hub is broadcasting with an older encryption mode, usually WPA or WPA2 with TKIP, kept around for compatibility with old gadgets. It does not mean anyone has broken in. Sign in to the hub settings, switch the wireless security to WPA2 (AES) or WPA3 where your hub offers it, and the warning clears once devices reconnect.
Key Takeaways
- The weak security warning means the hub is allowing an older WPA or TKIP encryption mode, not that the network has been hacked.
- Setting the hub's wireless security to WPA2 (AES) or WPA3 where available clears the warning once devices reconnect.
- Changing the default sticker passphrase and switching off WPS close the two most realistic gaps in a home network.
- Virgin hubs are secure once configured properly; the practical risks are weak or over-shared passphrases, not exotic attacks.
- A VPN adds a genuine second layer by encrypting the traffic itself, although it does not change the hub's own settings.
The warning means old encryption, not a hacked network
Since iOS 14, iPhones and iPads have graded the security of every WiFi network they join, and the weak security label appears whenever a network allows the older WPA standard or the TKIP encryption method. Both date back to the early 2000s. They were fine in their day, but researchers have since found weaknesses in them, so Apple now calls them out, and Windows shows a similar message for the same reason.
The Virgin hub side of the story is compatibility. Hubs can run in a mixed mode that accepts both the modern WPA2 (AES) standard and the older WPA/TKIP one, so that ancient gadgets can still connect. A hub that has been running that way for years keeps advertising the old standard, and the iPhone dutifully reports it. Nothing about the message means someone has broken in; the phone is grading the lock on the door, not reporting a burglary. The wider background on Apple's WiFi warnings, including the privacy warning that sometimes appears alongside this one, is covered in our guide to weak security WiFi messages for Apple users.
The fix is switching the hub to WPA2 or WPA3
The real fix lives in the hub settings, not on the iPhone. Sign in to the hub's admin page from a device connected to the network; on a Virgin hub that means browsing to 192.168.0.1 and entering the settings password printed on the base of the hub. If the page will not load, or the sticker password is long gone, our Virgin Media Hub login guide walks through the address, the password and the common login problems.
Once inside, find the wireless or WiFi security settings. The exact menu names differ between the Hub 3, Hub 4 and Hub 5, and Virgin does not expose identical options on every model, so treat this as a description of the setting rather than a precise path. The option you want is the security mode. Set it to WPA2 with AES (sometimes written CCMP), or to a WPA2/WPA3 mode where your hub offers WPA3, and steer away from anything that mentions TKIP or a WPA/WPA2 mixed mode. Save the change and let the hub restart its WiFi.
Devices reconnect automatically on the stronger standard, and the warning disappears. An iPhone occasionally holds on to its old assessment, in which case forgetting the network and rejoining refreshes it. One honest caveat: a genuinely ancient device that only speaks TKIP, an early-2000s printer for instance, may fail to reconnect after the change. Kit that old is worth retiring rather than a reason to keep the whole network on weak encryption.
Change the sticker passphrase and switch off WPS
While signed in, two more changes earn their keep. The first is the WiFi passphrase itself. Every hub ships with a random passphrase printed on the base sticker, and that sticker has usually been photographed, read out to visitors and copied into phones for years. Changing it to a long passphrase of your own, three unrelated words with a few numbers works well, means you know exactly who holds the key, and it evicts every device that was using the old one.
The second is WPS, the push-button pairing feature. It is convenient, but the PIN-based part of the standard has a long-known weakness that lets an attacker within WiFi range try combinations until one works, and almost nobody uses WPS day to day. Where your hub's settings expose a WPS option, turning it off removes that door entirely. Not every hub firmware shows the toggle, so its absence is nothing to worry about.
The honest picture on Virgin hub security
Scare stories aside, a Virgin hub running WPA2 (AES) or WPA3 with a strong, unique passphrase is secure enough for any home. WPA2 with AES has no practical break that matters for a domestic network, and WPA3 tightens things further. Virgin's hubs are not the weak link once they are configured properly.
The realistic risks are far more mundane. A passphrase that has been shared with half the street over the years, a default password still matching the sticker after the sticker featured in a family photo, a guest's compromised laptop joining the main network: those are the ways home networks actually get misused. It is also worth skipping the security theatre that older advice recommends. Hiding the SSID does little, because freely available tools list hidden networks anyway, and MAC address filtering mostly punishes you with admin every time a new device arrives. The hub's connected devices list is the useful tool here; a scan through it every so often, and a passphrase change if anything unrecognised appears, covers what those tricks only pretend to.
A VPN encrypts the traffic itself as a second layer
The WPA setting protects one specific thing: the radio link between your devices and the hub. A VPN works at a different layer entirely. It encrypts the traffic itself, from the device all the way to the VPN provider's server, so what you browse stays unreadable to anyone on the local network even where the WiFi security is weak, and your ISP sees an encrypted tunnel rather than the sites you visit.
That makes it a genuine second layer rather than an alternative. A VPN does not change a single setting on the hub, so it is no substitute for the WPA2 or WPA3 fix above; run it on top of a properly configured hub and the two cover different gaps. The same layer also travels with you, which is where it earns its keep most, on hotel, cafe and airport WiFi where you have no control over the router at all.

The guest network keeps visitors and smart kit at arm's length
Where the hub supports it, the guest network feature is the tidy answer to sharing your connection without sharing your keys. Visitors get internet access on a separate network name with its own password, and their devices stay away from your main network, so a compromised phone in someone's pocket never sits alongside your laptop and network drives.
The same separation suits smart home kit. Smart plugs, cameras and budget TVs are routinely the least-patched devices in a house, and parking them on the guest network limits what they can reach if one misbehaves. Give the guest network its own strong password rather than recycling the main one, and the arrangement largely looks after itself.
A brief WiFi dropout after the change is normal
Switching the security mode restarts the hub's WiFi, so every device drops for a minute and rejoins; that is expected rather than a fault. If the network is misbehaving beyond that, drops that keep happening or no connection at all, that is a separate problem from the security warning, and our guide to fixing Virgin Media WiFi not working works through it step by step.
