My Z70 Lenovo Tablet can't access wifi without a wireless booster

2017-10-25, 23:30 PM

Please could someone help me with a problem I have had for the last 18 months. My Z70 cannot fully obtain a good wifi signal when my router is only a few feet away.  My 13.3" HP can deliver blistering speed from the same distance.

 

So I had to purchase Netgear Wireless-N DualBand which connects into my USB port and yes it does work. The retailer I bought it from John Lewis in UK were not at all helpful. They said they could send it away for inspection and could take up to 3 months.

 

Now can anyone advise if there is a faulty wireless card in my machine that needs replacement, or something else maybe?  I am lost and would really appreciate some help from Lenovo  what to do.  I cant use it outside my home, it just won't connect to any wireless signal.

 

I bought in August 2015, upgraded to Win10 and the wireless worked fine for 6 months, but gradually deterioated over time. 

 

Thanks.

 

Pete

I dont know about this tablet but the wifi in some devices is very susceptible to interference from other nearby signals (I've seens this myself on a tablet and a laptop before). Routers in the UK mostly use one of 3 channels by default (1, 6 or 11, I think) so it is not uncommon for those to get crowded.

You could try installing a wifi analyser program on your laptop. (If you have another working tablet you could use that - there are good freeware programs for andoid to do it.) This will give you an indication if this might be the case for you. They often give a graphic display which is easy to read and understand. If it looks like a possibility try changing the channel your router settings to use one in a less crowded area of the spectrum.

You devices may adjust to the new settings automatically, but you might need to sign into the wifi again - it varies.

This can make a huge difference.

Windows shows the signal level of all routers in range and if the others are quite strong as well and on the same channel you could have problems. Its quite common problem in congested areas on the 2.4Ghz band and why 5Ghz is where many have moved to which support 11ac on newer notebooks as well.
