Wifi. Дальность приёма

Здравствуйте, друзья. Мой ноутбук преследует странность. Сейчас на нём стоит две системы: Windows 7 и Suse 13.2. Если я ухожу с ноутбуком на кухню (6 метров, 2 стены) от WiFi роутера, то Suse перестаёт его видеть. Ну как... Видит, конечно, но работать не может: говорит сигнал очень слабый. Причём проблема не только у Suse, но и у Ubuntu, которая стояла до этого. У Windows такой проблемы нет вообще: хоть к соседям уходи, всё едино: сигнал хороший, работает везде. Проблема, логично, в ПО, но куда копать и что гуглить я просто не представляю, потому что новичок откровенно полный и даже с терминалом работаю по мануалам. Я пыталась настраивать карту, но успеха это не принесло: со стандартным NetwokManeger я не дружу и чуть что меняю в его настройках, он просто отказывается работать с wifi. В Yast карта не настраивается в принципе: предлагается 3 программы на выбор, но карта настраивается только в Wicked, NM её не настраивает. Wickled не работает (или я просто не знаю, как с ним работать). Словом, замкнутый круг.
Я не хочу пользоваться Виной только из-за проблем с WiFi она меня просто дико бесит! Расскажите, пожалуйста, что гуглить хотя бы, а лучше дайте, пожалуйста, какой-нибудь практический совет)
