Hello,

In phone i checked Wi-fi network settings.

There i can see 192.168.1.1 is the default gateway ip.

There is a difference between the gateway IP and the IP address of your device.

Since it works on your laptop, open up CMD and type

ipconfig

And let me see the output.

Here is my ipconfig output.

Guys I think the issue is due to default gateway .

 

Scenario is that I have a Wi-Max connection and I have used 2 router.

1st router dooesnt have a Wi-Fi port So i have used 2nd ADSL 2 router for Wi-Fi.

May be this is root cause Why I am not able to get Wi-Fi on my phone.

Hello,

Guys I think the issue is due to default gateway .

More or less; Your Android seems to have its wlan0 interface (wifi) with a IP address that is in use by your router!

Before anything else, I wanna fully confirm this so on your Android (which is connected to the wifi) go ahead and open terminal emulator and type:

ip addr show wlan0

This will confirm.

Guys sorry for late reply.

Here is the screenshot of ip addr show wlan0.

If I'm reading everything correctly, your phone has the same IP address as your laptop. This is a problem. Are you using DHCP on your router and/or do you have any IP addresses manually entered into either your laptop or phone?

I am using a Windows PC also in this network.I checked ip address of that system too.It says IP as 192.168.1.101(Preffered).

Also i haven't configured any IP manually..About DHCP I am not sure about it.

Try opening the command prompt on your PC and type the following:

ipconfig /release

ipconfig /renew

That should tell your PC to find a new IP from your router that is not in use by any other devices.

As a test you could try shutting that PC off and testing your phone to see if the issues go away. If they both have 192.168.1.100 you will have problems.

 

I tried using only my phone connected to that network,but still no luck. :(

      I'm too old to return to the "good old days" when I was installing custom ROMs and tinkering with my devices - now I just want to turn it on and use it. I've read that banking and payment apps work on Murena /e/OS (I'll have to check the ones I use) and I also really want to support Fairphone 😉

    • NVIDIA announces 35 new AI HPC supercomputers across Europe

      By Fiza Ali · Posted

      NVIDIA announces 35 new AI HPC supercomputers across Europe by Fiza Ali NVIDIA has announced that 35 AI high-performance computing (HPC) supercomputers are planned to open throughout Europe this year. This marks what the company describes as the largest single-year expansion of AI infrastructure in the history of the continent. These new systems, unveiled at ISC High Performance 2026, will be placed at a number of national supercomputing centres, AI factories, and research institutes to provide advanced computing resources to more than three million researchers. Describing AI, NVIDIA founder and CEO Jensen Huang stated, "AI is the new instrument of science, and Europe is building the infrastructure to put it in the hands of millions of researchers." Built on NVIDIA's Blackwell and Hopper architectures, the new systems will support research in climate science, healthcare, clean energy, quantum computing, and other scientific fields. Among the major projects are the Barcelona Supercomputing Center's MareNostrum 5 AI upgrade, BavariaAI's Blue Swan platform in Germany, Italy's IT4LIA AI factory, Germany's HammerHAI project, and Sweden's Mimer AI Factory. The Barcelona Supercomputing Center plans to expand MareNostrum 5 with NVIDIA GB300 NVL72 and GB200 NVL4 systems. In total, the BSC expects to deliver up to 20 exaflops of AI training performance and 33 exaflops of AI inference performance. This increased computational capability will support research efforts related to climate modelling, biotechnology, energy systems, etc. Furthermore, as part of the IT4LIA project, more than 8,000 GPUs, each based on NVIDIA’s GB200 NVL4 architecture, will be used in Italy. This represents one of the largest AI factory initiatives announced to date. Additionally, the Blue Swan platform from BavariaAI will include about 1,000 GPUs to help develop multimodal AI models for use in the medical field, robotics, and various areas of scientific research. NVIDIA also emphasized in the announcement how rapidly growth of accelerated computing usage is taking place within both energy and climate-related research. The company said Siemens Energy uses NVIDIA-powered technologies to significantly accelerate the process of designing and simulating hydrogen-capable gas turbines. Using those same acceleration technologies, Siemens was able to reduce simulation time by up to 77 percent. The company also highlighted several quantum computing initiatives across Europe. CINECA, EuroHPC, and Pasqal are integrating a quantum processing unit into Italy's CINECA supercomputing centre using NVIDIA's CUDA-Q platform. Meanwhile, researchers at Germany's Julich Supercomputing Centre recently simulated a universal 50-qubit quantum computer on the JUPITER supercomputer. The announcement demonstrates Europe's continued commitment to building out its infrastructure supporting AI and supercomputing as governments, research organizations, and technology companies compete to build out their respective computing capacities and secure their positions in advanced scientific research.
