Issue about accessing wifi rooter

[mahesh]

Dear all,
Previously I have been using Ubuntu 21.10 Imprish for a long time. Today i installed Ubuntu LTS 22.04 Jelly Fish to an another Asus Vivobook X1502ZA laptop. I am dealing with strange error. I am using RT-N12+ Wiriless-N300 3 in 1 Wifi rooter. When i try to access this modem from Imprish there is no problem and accessing internet correctly. But this time LTS Jelly Fish causing this issue and can not access this router. Is there a specific setting for this issue or another reason possibly the regional. Any ideas i would be much appreciated...
