hi ... I have a question
I've used ADSL for 2 years until yesterday I just change ADSL to fibre max (700-900m)
Do I need to upgrade the modem or router to the new one?
because when I used lane cable and connect with a laptop and test the speed it shows me 700/700 that's true
but when I test the wifi speed with another device or mobile the speed down to 100-200 only!!! Shocking!! so different!!
Could you tell me how can I do?

Wifi is unable to reach the speeds that you can using a ethernet cable, so changing modem won't help sorry.

thats actually ok for wifi - especially for a phone.
Wifi cant go as fast. Most devices will see 100-200Mbit on 5ghz wifi.
Higher end devices (macbook pro, flagship phones etc) may see about 300.

Welcome to the Vodafone Community.
The modem could be part of the issue but you would need to check with your modems user guide and check what technology is supported.
Wired will always give you the fastest. For older machines they might be limited to approx 100Mbps.
Your modem may have settings for both 2.4GHz and 5GHz (check with the modem model online or via your user manual) each have pro's and con's.
Standard | Frequency | Theoretical Speed | Real World Speed |
802.11a | 5Ghz | 6-54 Mbps | 3 - 32 Mbps |
802.11b | 2.4Ghz | 11 Mbps | 2-3 Mbps |
802.11g | 2.4Ghz | 54 Mbps | 10 -29 Mbps |
802.11n | 2.4Ghz | 300 Mpbs | 150 Mbps |
802.11n | 5Ghz | 900 Mbps | 450Mbps |
802.11ac | 5Ghz | 433 Mbps - 1.7 Gbps | 210 Mbps - 1 G |
