    Hello, there is such a problem I have a Huawei b315 Router and everything was Ok, later I did not use it for a long time and now I wanted to use it, I inserted the card into the router and turned it on and here there is a problem because I do not have Wifi and the router does not light up the WiFi LED . I thought that the diode could burn and the signal could be but there is nothing I also tried to reset the router probably three times or nothing, I have no more ideas will you help me? Still in the margins I connected it to a laptop and made router configurations and it also did not help

    In the settings find and restore default settings. WiFi in the panel appears as enabled.

    In addition, you have a weak LTE signal. You have no problems with the internet?

    It is normal that in 90% of locations in Poland there is a weak LTE signal, especially in Play. Therefore, external antennas are used, but another 90% of users count on a miracle instead of buying and using a proven directional antenna. In Play on B315 you must first check all LTE bands, LTE signal parameters on them, BTS CID and speed. In addition, do not mix the range of Play voice offers because they use national roaming in LTE (Orange and Plus) and on 3G from three operators (DL limited to 3Mb / s) with Internet tariffs that work only on the LTE and 3G Play home network. And WiFi in B315 probably fell since the management panel appears as enabled. Router under warranty?

    Then you can connect another router as an AP to it, or buy another one.

FAQ

TL;DR: Huawei B315 Wi‑Fi missing? "In 90% of locations in Poland the LTE is weak," which affects speed, not Wi‑Fi. If Wi‑Fi is enabled in the panel but the Wi‑Fi LED stays off, the radio has failed—add an external AP or replace the router. [Elektroda, matek451, post #17266685] Why it matters: This FAQ helps Huawei B315 owners diagnose no‑Wi‑Fi symptoms, restore service, or choose reliable workarounds.

Quick Facts

Why is my Huawei B315 Wi‑Fi LED off even though Wi‑Fi is enabled?

If the web panel shows Wi‑Fi enabled but the LED stays dark, the Wi‑Fi radio failed. Ethernet continuing to work confirms a Wi‑Fi‑only fault. Add an external access point or replace the unit. Expert quote: "WiFi in B315 probably fell." [Elektroda, matek451, post #17266685]

How do I reset the Huawei B315 to factory defaults?

Use the hardware reset to restore defaults.
  1. Power on. Press and hold Reset with a pin until LEDs blink.
  2. Wait for reboot. Connect by Ethernet. Open 192.168.8.1 in a browser.
  3. Log in. Run Quick Setup. Re‑enable WLAN and set SSID and password. ["Huawei B315s-22 User Guide"]

How can I check if Wi‑Fi is enabled in the B315s web panel?

Connect by Ethernet and browse to 192.168.8.1. Sign in, open WLAN/Wi‑Fi settings, and ensure Enable WLAN is checked. Confirm SSID broadcast is on and Security is WPA2‑PSK. Apply changes and retest for the SSID. ["Huawei B315s-22 User Guide"]

Can the B315 still provide internet over Ethernet if Wi‑Fi is dead?

Yes. The router can route internet via LAN even when its Wi‑Fi radio fails. The thread author confirmed cable internet works with no Wi‑Fi present. Use LAN ports for PCs or for feeding a separate access point. [Elektroda, Krystian7363, post #17266394]

How do I add another router or access point to regain Wi‑Fi?

Connect a standalone access point or a spare router to a LAN port. Enable AP mode on that device following its manual. Keep DHCP on the B315 and disable its Wi‑Fi to avoid interference. This restores wireless while the B315 handles LTE. [Elektroda, makosuu, post #17266711]

Could a firmware update fix missing Wi‑Fi on the B315?

Sometimes updates clear configuration glitches. Log in to the web UI, check for Updates, and install the latest firmware. After updating, verify WLAN is enabled and the SSID broadcasts. Reboot once. If Wi‑Fi still does not appear, the hardware is faulty. ["Huawei B315s-22 User Guide"]

Does a weak LTE signal cause Wi‑Fi to disappear?

No. LTE quality affects internet speed, not whether the router broadcasts Wi‑Fi. An expert noted weak LTE is common, but your Wi‑Fi failure is separate. Improve LTE with antennas; address Wi‑Fi by repair, AP, or replacement. [Elektroda, matek451, post #17266685]

How can I verify the B315 is broadcasting an SSID?

In the web UI, confirm SSID broadcast is enabled under WLAN. Set a simple test SSID and WPA2‑PSK password. Scan from multiple devices and a Wi‑Fi analyzer app. Change the channel and apply. If no SSID appears, treat it as hardware failure. ["Huawei B315s-22 User Guide"]

What are my options if the router is out of warranty?

Use the B315 as an LTE modem and add an external access point. This is the fastest path back to Wi‑Fi. If you prefer a single box, replace the B315 with a modern LTE router. [Elektroda, makosuu, post #17266711]

What are the Huawei B315s Wi‑Fi specs and limits?

The B315 provides 2.4 GHz 802.11b/g/n with up to 300 Mbps link rate. It lacks 5 GHz, so crowded 2.4 GHz can hurt throughput. Use WPA2‑PSK and a unique SSID for stability and security. ["Huawei B315s-22 User Guide"]

What do the Wi‑Fi LED states mean on a B315?

Typical meanings: Off means WLAN disabled. On means WLAN enabled. WPS pairing uses a blinking pattern during setup. If Off while WLAN is enabled in the UI, suspect a failed radio module. ["Huawei B315s-22 User Guide"]

How can I improve LTE performance while using Ethernet or an external AP?

Test all LTE bands and record signal and speeds. Add a directional outdoor antenna aimed at the best BTS. On some Play 3G roaming, download is limited to about 3 Mb/s. Lock bands and retest for the best result. [Elektroda, matek451, post #17266685]
