What should i do?

[wayi]

I am using thinkpad W540. I have been using it for almost a year but it seems like the device catches the wifi a bit weak, should I replace the network card?

Intel AC-7260 is probably the best for it, FRU 04X6007

Hy RBS
how does the AC 7260 compare to the Intel Centrino Ultimate-N 6300 (3x3 AGN) ?

The (3x3) 6300N is max 450Mbps, the (2x2) AC-7260 is max 866Mbps and also includes Bluetooth 4.0.
The above AC-7260 (when bought as a proper FRU) is officially supported in the W540 (and other xx40) frubom lists.
Also, the AC-7260 is PCIe format with standard antenna-connectors, newer cards have some M.2 format and smaller antenna-connectors.
When you upgrade to an AC-card, it would be advisable to also have an AC router.

When I originally bought mine, it was an (ASUS re-badged) T-Mobile TM-AC1900 router for only $50.
But after a (bit complicated) firmware conversion and upgrade with Merlin, it is now a real ASUS RT-AC68U, worth at least double that.

To have all the (and possibly way too much) info for (initial) AC-7260 hiccups, and how to solve them, see this long post

As I don't have/use any Bluetooth devices, I never installed any BT driver.

As for comparing 6300N vs AC-7260 I leave that to others, as I have no problems with either.
I have an X230 with 6300N, plus some X240's and a T440p with AC-7260 and an X250 with AC-7265.
Since we have FTTH (Fiber To The House) internet, we all get great wifi with average Down/Up speeds of 90/20 Mbps.
If I would throw a bit more money at my ISP, I could even get 500Mbps or 1Gbps, but who needs that?

I was asking because I have an 6300N on my W530 and something similar on my X230, and a new AC one, 9000 series I think on my P1
the W530 and X230 modules work like a charm, good speed, fast connection, fast to find wireless connections, everything works PERFECTLY
the P 1, ....well....sometimes I feel like using it to crack nuts with it, ...The level of misery I experience with the wifi card on that machine (the P1) far far exceeds anything I experienced so far, not even the old days of 56k connections are not that traumatizing compared to this new rubbish. and I dont understand why, it was supposed to be better not worse. sometimes I can lose 5 minutes or more to manage to connect the P1 to the same wireless sources that it takes to the W530 and X230 less than 5 seconds. on many occasions, more than half the times, it requires me to manually click on connect several times, like 3 or 4 times before a connection is established, its unbelievable.

That would be the Intel AC-9560.
Apparently a not unheard of problem.
You have 2 options:

#1: Select Start > Settings > Network & Internet > Status > Network reset > Reset now > Yes to confirm, reboot and test your wifi.

#2: Cold boot, go straight into BIOS, select F9 to set BIOS to Default, reboot and test your wifi.
