I have changed cable again, I tried with 1.8m cable which the internet provider has packed with router. Rooter is Huawei
NE40-X3, network card is onboard, but I have tried with external tp-link card too. I have tried with other computer too.
Is there a limitation in ram or swap partition size?
Could you tell me where could I find that logs which you are asking?
