Is 1&1 Down? Live status & outage reports

Service info and troubleshooting

Internet Connection Drops Randomly

Random disconnects usually come from a faulty router configuration or a line sync issue. First, reboot your router by unplugging it for 60 seconds — not just a soft restart. If drops persist, log into the 1&1 router interface (typically 192.168.2.1) and check the DSL line statistics. A high number of CRC errors or a low SNR margin points to a physical line problem. Contact support and ask specifically for a line test, not a generic ticket.

No Mobile Signal Indoors

If your 1&1 mobile SIM shows no signal or stays on emergency calls only, the issue is often a network registration failure. Toggle airplane mode off and on, then manually select the network under SIM settings instead of leaving it on automatic. If the problem repeats, check whether your SIM is properly activated in the customer portal — a provisioning delay after a tariff change can silently kill service.

Login Fails in the 1&1 Control Center

A failed login to the Control Center app or website usually means a cached session conflict or an expired password token. Clear the browser cache and cookies, then try an incognito window. If the app throws an error, force-close it and reinstall. For persistent lockouts, use the 'Forgot password' flow — the reset email sometimes lands in spam.

SMS Messages Not Delivered

Undelivered SMS is often caused by a full message center or an incorrect SMSC number. Check your phone's message center number — for 1&1 it should be +491722270333. Also verify that the recipient's number is saved in full international format.

Payment Not Going Through in Portal

• Make sure your saved payment method hasn't expired — an outdated card expiry date silently blocks auto-payments.
• Disable any browser extensions that block scripts; they can break the payment form.
• Try a different browser if the 'Pay now' button stays greyed out.
• If a SEPA direct debit failed, check whether your bank blocked the mandate and reauthorize it manually.

App Interface Freezes Mid-Session

The 1&1 app tends to freeze when local cache grows too large. On Android, go to App Settings and clear cached data without clearing account data. On iOS, offload the app and reinstall. If the freeze happens specifically on the invoice screen, the PDF renderer is likely timing out — open the invoice through the web portal instead.

High Ping on 1&1 DSL Line

Elevated latency on a DSL connection often comes from interleaving being enabled on your line. Log into your router admin panel and check if fast path mode is available — switching from interleaved to fast path can cut ping from 40–50 ms down to under 10 ms. If the option is locked, request a profile change through customer support.
